Backdoors ?

backdoors are things that leakers who want to ruin your server put in to their leaked addons. basically, it can give the leaker a certain permission like giving them superadmin when they join the server. you can find these backdoors in lua files inside of the addon, so its always best for checking for them in leaked addons before putting them into your server. you can usually find these backdoors in the form of steam ids or where it mentions superadmin. thats pretty much all i know, other people can elaborate on this and fix it a lot.
