It's well beyond me how a "bitcoin mixer's" developers could be so incompetent.
Don't mix up your own incompetence with someone else's. You don't use mixers to "clean" your coins, but to obfuscate your inputs and break the transaction trail on the blockchain. Obviously, by doing that, you end up with "someone else's" coins that might be linked to some shady activities.
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.
That's nonsense! Jumping to conclusions about being on an FBI watchlist due to using a mixer is a bit of a stretch.
