TLDR; privacy is a bad thing.

Pretty disappointing that mixing coins is "officially" an illicit activity now. Doesn't it sound oxymoron, though, to exchange centrally and use a mixer? Pick a side; you can't protect your privacy if you don't have any.
Although I do wear the ChipMiner signature, I have always said that for the amounts that I assume most forum users you can do a better job doing it yourself using an exchange or 2 that does not require KYC and a few privacy based coins.
Mixers are convenient, but far from the only way of hiding where your coins came from.
