Question: At what certain amount of deleted post will cause a permaban? I lost count because I delete all this notification on my message because it's already annoying at that time.
Only the officials from the forum like Global moderators or admins can give you a specific answer to the question but from my experience and observation since all these years I may say that there are not actual number to it. The forum also does not have any point system too to ban you automatically. The mods manually ban a user. In that case it entirely depends on the judgement of the mod who is banning you.
