I think this puts to rest those conspiracy theories about Chipmixer being a honeypot operated by government agencies.

I doubt this will affect regular users but there is a possibility they could try to shut down this forum. There is already a similar precedent when Deep Dot Web was seized by the FBI. It would be an overreach for them to go this route but if they really wanted to shut down BitcoinTalk this would be their best opportunity. As far as I'm aware Chipmixer didn't advertise anywhere else besides this forum.
