That's an interesting angle to cash out... just start sending to 1,000s of addresses - who's to say which addresses are owned by the criminals, and which are owned by other people? They'd get less than cashing it all out themselves obviously, but it would take forever to unravel what actually happened (if possible ever)

This is essentially what a tumbler does

The suggestion is a philanthropic variation of a tumbler.

Funds like this can be frozen when 51% of mining pools start censoring transactions. Pools are now beginning to do this. I expect there will be a lot of BTC like this that starts to realise they need to be trying to dump it / escape into monero as quickly as they can

If someone pays you in cash, do you really look up the serial numbers of all the bills you receive?

This isn't so far fetched. Cash registers already have Internet connections and can be outfitted with cameras to record all bills going in, except maybe those inserted in a stack. And ATMs might already be recording serial numbers of dispensed bills. Essentially they might/could do with currency what they do with license plates, which is track where everything goes and at what times.

Like 0 cash registers I have ever seen employ this.

Here’s an interesting question — if you receive BTC from one of these addresses as payment for something, do you refuse it? You know it’s stolen and you might worry someone else who you might pay in the future would be able to track down that it’s stolen, so do you ask for “clean” BTC that isn’t linked to known theft? I don’t necessarily know the answer here. This is something that you can’t do with paper bills

Coinbase suspended my merchant account from receiving funds about 5 years ago without warning. I was receiving funds as any merchant would, with the occasional payout to bank. I had no idea why they suspending receiving, and as some already know, their support was not very supportive. The only reason I could think of is possibly receiving tainted funds?

It's possible to swap into monero without using any KYC exchange, but that requires liquidity. So it could take years.

There's a difference between pools not accepting txs in their mempool, and pools refusing to build on other miners' blocks that contain them. Pools are beginning to do the former (which doesn't cost them), not the latter (which would cost them dearly). Only if a majority of hashpower does the latter will censoring be effective (and then no longer cost them again).

Can one even refuse it? If someone just sends tainted coin to my address, am I screwed?

Not an answer to your question but BTC does not really have wallets. Someone just signs a number of BTCs with his private key and your public key so the only way to sign it again is with your private key. This is essentially how it "moves" to "someone". Some other DTLs (blockchains) actually have wallets/accounts with properties where you can disable incoming funds/add a name/change the password and such stuff.

You could use also do that to embarrass/blackmail politicians or other prominent people. Imagine the threat "You either do what I want or I'll send you 1 million dollars" :)

What politicians accept Bitcoin as donations?

What's wrong with simply returning it? Any "tainted coin tracker" could easily build in a mechanism for detecting that

Would you return stolen goods to the thief? How about return it to the owner/authorities. May not be simple but certainly better than sending it back. If all else fail there are black hole addresses to forever lock the BTCs.
