There's no point in hiding tools you can do harm specifily with Amxmodx. The idea of protecting yourself from that kind of action is just the same as with websites. If you don't trust a website you shouldn't load the page, if you don't trust a game server then don't connect there. As of if you can get a virus to client's computer via website and browser so you can from a server by just showing the same website with show_motd.
