Given you saw that post it was a ban given by someone else for advertising (or basically just joining to advertise another site of the like). Usually we don't explain bans of other members as that's private, but given you saw the post, well, there you go!
I'm not sure whether to ask you or not, but this guy called FishAml was banned only today when he joined, he only made one post which was later deleted. Do you know anything about this? If I wasn't supposed to ask you, I just want to apologize.
