Well, this whole thing sucks.  While their last forum activity was on November 12,  it's unclear if they even saw your first message. However, I think it is important to point out that they seem unresponsive across all communication channels. I mean, we have no clue what's actually going on there.

Unfortunately, we can't really do anything else right now. Obviously, the best thing is to caution community and to let everyone know what's happening so they're careful if they use their services until we hear something from their side!

Hopefully CryptoMixer will get back to us soon so we can get this fixed.  In the meantime, spread the word so nobody else gets burned.
