It is inevitable that most if not all mixers will be used for (or will be attempted to be used by criminals for) nefarious purposes
It is inevitable that most if not all banks have been used by criminals for nefarious activities. How many closures have we had as a result of that? Even when banks engage in scams, they just get a slap on the wrist.
Sinbad,io probably does not have too much time before various law enforcement agencies get together to organise the shutdown of their website and try to arrest the owner/operator on money laundering charges. If criminal activity as taken place on an industrial scale and almost zero protocols were put in place to either reduce, minimise or eliminate the risk of illegal activity by the owner/operator they will end up facing serious criminal charges.
This is a grey area as minimizing or eliminating risk by mixers would mean censoring transactions just as centralized exchanges do and would lead to even more centralization of bitcoin channels.
The government can play Russian Roulette with mixers but the end is definitely not to put a stop to illegal activities.
