Please stop promoting the idea that taint exists. I consider making people believe it exists an attack on Bitcoin, and it may very well be the only way for governments to stop Bitcoin from succeeding. Don't fall for it.
Try telling that to all people who are using shitcoins like ethereum, that now have 52% of all blocks being OFAC compliance, it's always growing all the time according to mevwatch.info, and now it has built in censorship for transactions!
You can also write your government and all other governments and centralized exchanges who all say that tainted coins exist.
Welcome to the crypto main stream narrative, I hope you like it

I sure don't like this, but closing my eyes won't change the fact that people can run into problems if someone catches them with coins coming from some hacks and exploits.
One solution is to stop using centralized exchanges and services, that will reduce potential problems, but you can't avoid them totally.
We could also use Lightning Network or second layer solutions that can also break connection with your previous transactions if done correctly.
Perfect solution would be if Bitcoin would implement protocol based privacy changes, but I am not sure this will happen in next few years.
