mikopotato: I see, Any other offense resulted in a ban? Like harrasment?
No idea.
I do have to say that it is possible for bans to have been happening every day, but not to people I notice on the forums. Bans are more noticeable when they happen to active people, especially if we can't fathom a reason for their bans. If tinyE stops posting for a week for example, we will wonder what happened to him, but if ExiledUser doesn't post, few, if any, will wonder what happened to him.
GOG does not publicize their bans, and I do think they are correct in doing so, so it falls to each user to decide whether he wants to say that they were banned for reason X. Few do so.
