Right. People need to understand that 100% anonymity doesn't exist. All mixing services offer is an additional layer of privacy.

In the end, for me all that matters is getting rid of the exchange taint, and that's what mixers do the best. Even if certain agencies still manage to spot your movements afterwards, they can't be sure that it's actually you, and that's the beauty of it. Try to prove it's me. It's not worth the time and effort of digging any deeper into it with how it costs more in time and resources than they would gain from it.
