Hello.
As in the thread title - this feature was removed after the revamp going from version 3 to version 4. It was a very convenient one - you could make a custom group for a user that reaches the ban treshold set in the forum and then make a custom category/subforum for that person to appeal the ban. From version 4 forwards this is no longer possible as reaching the infraction treshold results in blocked access to the entire forum, forcing the banned user to use other means of communication to appeal their ban.
