@[LFG] RampageKing11 As I have already said here in comments even the comment before yours... "This was release before ULX had it's own thing, also this has Password failed message and supports other admin mods."
@[HW:O] SlayerLegendz this makes it so the person doesn't even start downloading the files or connecting when they are blocked, so it doesn't block others from entering the server. Also it has support for other admin mods.
Probably no as basically no global ban add-on has a local table of the bans, which is understandable as it would be a lot of data to fetch every map change etc. I might take a look at another way it can be done at some point, but no guarantees.
