Kinda hilarious how this sockpuppet account just woke up from the dead and is now attacking the OP.
Who is behind these accounts attacking Cowboy310? I wonder.

.. If the originating wallet is linked to crime, they have every right to hold the funds under AML regulations
Got a proof OPs funds are linked to some crime? If not then I suggest you keep shut and not make baseless accusations. MrCryptoMixer is running an unregistered and what looks to be an illegal mixing operation. Since when did these shady mixers start caring about KYC/AML regulations?
Illegal or not, Cowboy310 has full right to get his funds back if they are with MrCryptoMixer.
At first I was thinking MrCryptoMixer isn't in the wrong here and OP was a victim of some sort of clipboard or DNS hijacking attack, but these attacks from sockpuppet accounts are making me think that maybe there's a possibility that MrCryptoMixer is trying to take advantage of Cowboy310's situation?
Can't say with certainty, and I don't think we will ever get to know what the truth is here.
In any case, Cowboy310, you aren't getting your funds back. Sorry for your loss.
