The user was banned for an entirely different reason, not for the ones mentioned in this thread. No one noticed that this service was advertising a mixer and offering mixing services itself. That is precisely why the thread was deleted and the user was banned.
A bit unrelated to the topic at hand, but doesn't the introduction of the mixer ban mean we need the welcome message added for new members a lot more?
Most other rules we have are common sense, while I will like a welcome message to be the standard, users can easily stay without getting into trouble. But knowing not to advertise any mixer at all in a crypto forum is not common sense but discussions you'll expect to find here. I think users should be informed that they would get in trouble if they promote them in any way on the forum.
