I understand the idea that the forum does not want to become a platform for advertising suspicious services that are engaged in scams. But banning absolutely all mixers on the basis that some of them were engaged in such illegal activities is very unfair to those services that do not do this. Some casinos also deceive their users, do not allow them to withdraw winnings and much more. But they are allowed to advertise on the forum. That is, the logic here is quite ambivalent, in my opinion.
I do not understand why you would consider comparing a casino with a Bitcoin mixer. An online casino will hurt the finances of an individual and will only help the government with taxes. Whereas a mixer will or can hurt the internal security of the government. I won't deny that fiat has been doing it for so long but fiat can be traced and mixer outcome is hard to be traced. I do not think that the new administration will be okay with mixers as it is still a threat in various ways to the US government. I also believe that Theymos will not be so inclined to allow these mixers to operate or advertise in the forum. Do remember that Chipmixer has a tainted past and all those who were part of that signature campaign are either hiding or are using their alts to be active here.
