This would mean that the address YoMix used too give me funds immedietly got detected as being connected to terrorism financing. It's well beyond me how a "bitcoin mixer's" developers could be so incompetent.
So I guess thanks YoMix for putting me on an FBI watchlist. Be warned anyone. If it's so easy for an exchange to detect a bitcoin "mixer" it sure as hell means that it's not an actual mixer.
AFAIK, the message given to you by uphold is the typical description when user caught using mixer to deposit on their platform. You check their ToS if they forbid the use of mixer to deposit since some centralized services that usually involves fiat as main currency is very strict on mixers. We have centralized service too in my country that doesn’t allowed funds coming from gambling, mixer and other platform which can be use to launder except exchange.
There’s no way to filter out Bitcoin that being watch by FBI since there’s no such sign like that to determine tainted Bitcoin unless you knew the watchlist of FBI.
