Random idea: USL, but for Bitcoin addresses

This is my rough idea for a Bitcoin change that would allow for a bit more fraud protection. I might write up a BIP later if I get around to actually nailing it down.
For those unaware, the Universal Scammer List (USL) is a page dedicated to keeping track of the usernames of scammers on Reddit. Basically, if you want to conduct a transaction with someone on Reddit, you should first check if they're listed as a known scammer.
My idea is to do the same with Bitcoin addresses. A decentralised database of blacklisted addresses would be kept by anyone running a full node. Any funds in the blacklisted addresses are deemed worthless.
For example, address A gets listed for hacking into an exchange and stealing coins. Any funds held by address A would be deemed worthless. If they send 10 BTC to address B, then the network would remember that address B has 10 BTC that is worthless. If address B originally had 5 BTC and was sent 10 BTC by address A, they would have 15 BTC, but the bottom 10 BTC would be deemed worthless. If address B sends 2 BTC to address C, then C receives 2 good BTC and B is left with 3 good BTC and 10 blacklisted BTC, but if B sends another 4 BTC to address D, then D would receive 3 good BTC and 1 worthless BTC, and the network would now remember that D has 1 worthless Bitcoin. Therefore, before accepting the transaction as payment for something, they would have to check to make sure that they are not receiving worthless blacklisted coins.
Miners could also choose to selectively refuse to mine transactions involving blacklisted BTC because any miners' fees collected from such a transaction would be blacklisted as well. This could mean someone trying to send blacklisted BTC is essentially broadcasting a transaction with a 0 sat/byte fee rate, meaning their transaction would probably be stuck in the Mempool for quite a long time, if not forever if miners refuse to mine it.
Whenever someone wants an address blacklisted, they would announce it to the public via any mechanism, and anyone keeping a full node can decide whether or not to blacklist the address. Therefore, anyone who disagrees with the blacklisting is free to accept the coins at face value or mine them into a block. If you don't agree with the evidence presented, then you are free to not blacklist them. Therefore, contested coins would only be accepted as valid payment by those who think the coins should have never been blacklisted in the first place.
This system would not be meant to help every single person who gets scammed with Bitcoin, but it would discourage large scale wholesale Bitcoin fraud. It would be ridiculous to expect all full-node maintainers to become arbitrators of all disputes, and consensus would never be reached on half of the transactions being processed. Node operators would also ideally not have to remember as many transactions involving blacklisted coins because miners would refuse to mine them (transaction fees collected would be in blacklisted coins), meaning they'd be stuck in the Mempool for long periods of time, reducing the speed at which they can be moved around, if at all. So the ledger of blacklisted coins would not have to be updated extremely often. Blacklisting would only happen for really big scams involving tens or hundreds of Bitcoin, like if an exchange got hacked or something.
Scams have effectively less than an hour to be discovered. 10 minutes for the deposit into the address in question, and more, depending on how many block confirmations something must have before others will accept it for transactions sell goods for it. Therefore, if a merchant requires 3 block confirmations, then they would give 40 minutes for the address to be blacklisted. If the buyer's address is blacklisted before the transaction to the merchant gets 3 block confirmations, the merchant would realise they've been sent blacklisted coins and not ship the goods. 40 minutes isn't a lot of time, but it's better than nothing.
This has the additional effect of encouraging people to wait for more confirmations. For low-value transactions, the risk is nominal because even if you were sent worthless coins, you're probably only out the price of a coffee. But if you're selling a house, you might want to wait for even more block confirmations.
Money sent around too much could be deemed "too late to blacklist" if there is a risk that it would result in too many innocent people's Bitcoin getting blacklisted.
This system doesn't refund the Bitcoin of victims, so poor security practices would still be punished by a loss of coins, but criminals would not be rewarded for their efforts either. The lack of reward (or the risk of a lack of reward) would hopefully make people less inclined to try and pull off the type of big scams that are giving Bitcoin a bad reputation!

What happens if bitcoin is sent to a random address that nobody owns?

If it’s just gone forever then wouldn’t this be a big issue give that the supply of bitcoin is limited to 21 million? What if all bitcoins are eventually lost to the void because of people messing up transactions?

Have there been cases of a hostage ransom involving Bitcoin?

Let's say a criminal were to walk into a upper middle class person's house, armed, and masked. Then they coerce the homeowner of using their credit card on their computer, and purchasing a bunch of Bitcoin and sending to a random Bitcoin address that can be accessed by the criminal later.
Has a case such as this been done, and how likely would the person be to get caught, if it were let's say up to $20,000, and accessed the money over a couple years.

Is it possible for a trojan virus to gain access to an email you never used on you computer?

Hello, yesterday I received an email threatening to email my contacts if i did not pay a certain amount of money to some random bitcoin address. Ordinarily I would not be worried about this, as it is likely just spam, but this email came from an old email i haven't used in years. I haven't logged into that email in about two years, and have never logged into it on my new computer. The sender said they got my email using a trojan virus from an adult website, but i'm more concerned about how it is even possible for someone to send or pretend like they are sending an email from my old account. If anyone can offer any insight or has received a similar email, i would appreciate any information. Thanks!

What prevents you from stealing using Shapeshift ?

Sorry I must just miss some obvious point, but if you use your MEW wallet address as the destination address and a random BItcoin address for the Refund Bitcoin address, considering you can find plenty of random BTC addresses on the chain, what stops you? And then you turn, for instance, someone's Bitcoin into Ethers for you. I'm sure I am missing something but what?

Unmasking anonymity

Every cryptocurrency owner should be aware that there is the possibility their identity and activity once considered perfectly secure may be revealed/ de-anonymized at some point.
Since decentralized Bitcoin cryptocurrency came into existence in 2008, people have been hoping that fast convenient and anonymous money not controlled by anyone would be used. Indeed, promising revolutionary ideas and technical solutions at the time were embedded in the Bitcoin concept. Today Bitcoin is the most popular cryptocurrency throughout the world. It carries a reputation for allowing users to operate in the shadows, but is Bitcoin completely anonymous? Almost a decade after its introduction, no additional anonymity mechanisms were implemented in Bitcoin.
The most important anonymity principle of cryptocurrencies is not only impersonality of a cryptocurrency wallet but also an impossibility of tracking connections via blockchain.Bitcoin, unlike a common bank account, provides its users with an opportunity to become a system member and manage financial resources regardless of anyone. An impossibility of blocking or confiscation of funds from an owner's wallet is a crucial advantage of decentralized cryptocurrencies.
However, the anonymity provided by Bitcoin is rather vulnerable. As well as the majority of well-known cryptocurrencies it is tied to distributed blockchain technology, which records every transaction and traces them back to their origin.
In other words, a privacy form which today is offered by Bitcoin, is confined to pseudo-anonymity: an individual is represented by an alias in a blockchain. Anyone can create a new and completely random Bitcoin address at any time, without the need to submit any personal information to anyone. However, this does not guarantee that connections cannot be revealed. When any payment is executed, its amount, remaining credits and all the previous and following transactions of the participants become available to everyone. Until the link between an analyzed address and a real identity is established, this information is abstract. But once an interaction with real world takes place (for example, IP-address, stock account, delivery address, etc. is identified), transaction history of a particular person can be definitely tracked. Moreover, there are other methods used for deanonymization, namely taint analysis, cluster analysis and volume analysis.
Therefore, the problem that every Bitcoin owner faces is that this cryptocurrency, as well as many others, is pseudo-anonymous rather than anonymous and lacks privacy. If you are interested, please stay tuned and in the next posts we'll discuss defenses against deanonymization attacks.
