ULX has a few whitelists already in place, such as restricting groups to only be able to add people to specific ranks, and only allowing people to ban specific SteamIDs. I was wondering if a blacklist could be added so that for example an admin can add a few SteamIDs to said blacklist under the command "ulx banid" and then the issue of admins banning people that are ranked higher then them using that command would be fixed.
Also it seems like it would be useful in some other situations as well, if for example you want people to be able to add to all groups accept one group.
Instead of having to whitelist every group you have on your server (some people have quite a few) you would be able to just add that one group to the blacklist and you would accomplish the task much faster.
