I have always had a problem with exploiters. I manage a group with 65K members and the biggest problem for my group is exploiters. I am a decent coder and I know a lot of things coding with lua. Although this may not be a "Question" I am still asking for you opinion(s) on this.
When a player exploits a game the sofware will execute all the scripts to the local player backpack. Using scripts like Infinite yield or nex3l admin. The script will make a GUI using Instances. I tried it once running the script while in roblox studio (play game then press test then run script) When I look in my PlayerGui there will be ScreenGui's called MEME or TOGLEBAR. My idea is that a script can sense those ScreenGui's and kick the player (if they have that gui) I am not sure how jailbreak does it but they have patched EVERY admin script type there is.
My concept:
local player = game.Players.LocalPlayer
local gui = game.Players.LocalPlayer.PlayerGui
while true do
if gui.ChildrenAdded then
player:kick()
end

If you're game is FE it should be pretty safe already and only danger would come from noclip, builder tools (client only though!) and Using remote events badly, I would focus more on remote events than client only stuff
Jailbreak is very vulnerable to exploits tho
okok so if you dont know jailbreak put some time into the exploit protection (no REALLY) but if ur looking for good exploit protection CBRO has the best. They "somehow" ( i know how) patched homejows.bin (its a btools exploit thats unptchable)
