CoreGUI problems

So there is a script that can ban all in my game and how could I detect it because roblox doesn’t allow anything to do with blacklisting stuff in CoreGUI (I think thats true) I was wondering if I could detect the keyword in the GUI that comes up and then it kicks them

Obviously there is a deeper issue so fix that instead, make sure all your remotes are secure

Oh I have something to detect if they mess with remote events.

As @lanjtlike correctly said, you should fix the main issue behind is. Secure your remotes which are probably being used to ban players(server-side secure them):

--example
function IsAdmin(player) 
	--returns if a user is an admin
end

BanRemote.OnServerEvent:Connect(function(player1, player2)
	if IsAdmin(player1) then 
		--run code
	end
end)

If you’re talking about that one solution that came out a few months ago there are ways to bypass it, please secure everything instead of trying to detect when they try to mess with something because there is always a way to bypass detection methods

Could you send me the solution so I can look into it

No because as I said before that isn’t the overall issue.
