Oh my goodness...quite a bit. The one I find was most helpful and got rid of all my spammers was the Question Mod. It's where when you sign up you have to answer a question. Other mods that I have include Arcade, Cash Mod, Easy Mod, Star Mod, Store Mod (took that one away till I upgrade), and a few more. Can't remember off the top of my head. lol I love mods and features!
