As far as I know, the BTT forum server is in America so that American regulations do not provide access rights for the Bitcoin mixer platform to promote on the BTT forum.
So that every staff, admin or whatever is on the BTT forum does not want to receive any more advertising promotions about the Bitcoin mixer platform, unless maybe they are ready for the risks taken such as being sought by Interpol or the CIA. Cmiiw
No not really
It's not like promoting mixers is illegal in the US
As long as they are not caught laundering illegal funds
Nothing is wrong with them or using their service
Theymos is just been cautious.
Practically, his cautiousness has brought the silence of Mixers in BTT, I don't think there's any running mixers related signature campaign on BTT presently.
I just hope there shouldn't come any link with these bad guys trying to use the mixing service for something illegal, if not, it'll foster the hunting down of most mixers.
So, the project team of these mixers should exercise cautioness just as Theymos to prevent any illegal services with their mixing company.
