We've received no warnings or requests to change policy from law enforcement regarding mixers.
I would prefer to allow them. I don't view using them as unethical, and I don't care about reputation. But this kind of thing is far from the core mission of bitcointalk.org, and the costs far outweigh the benefits.
It wouldn't be illegal to continue allowing mixers here. That's why we're able to offer a 1-month grace period. But allowing them has become too risky/problematic, and it's only going to get worse. Imagine 5% of all active forum users being sanctioned due to being paid directly by mixers, or all participants in a big signature campaign being targets of a search warrant, or our service providers suddenly banning us due to being "associated" with mixers, etc. I think that the crypto community is near the start of a multi-year squeezing campaign against mixers; similar to the cannabis industry in the US, or Operation Choke Point, or what happened with Backpage, or the deplatforming of Parler.
That's allowed unless the site is also a mixer due to eg. allowing BTC->BTC "exchanges" or advertising BTC->XMR->BTC exchanges as a way of mixing coins.
I don't anticipate the need for major new restrictions in the next couple of years, but it could indeed happen. Maybe Bitcoin will be banned in the US someday, and then I'll have to either shut down bitcointalk.org or find a way of moving it to some remaining territory of freedom in the world. That's the problem with centralized forums. I wish that more work was being done on creating decentralized, uncensorable, but also usable forums. I would love nothing more than to be able to shut down bitcointalk.org due to some decentralized solution making it obsolete. Find me a 501(c)(3) nonprofit working on this, and I'll donate to it.
Correct. And something can also be darknet without having a .onion. By "darket" I mean something that wouldn't be able to exist for long outside of the shadows because it's being suppressed by the state.
It's not a priority, but I might blank them at some point.
Since that doesn't have any real links to mixers, it may be OK. Probably we'll leave it alone at the start and see how it looks after a few months.
