well badder adder used to work for me but now u have to validate loads of adds...i dont know any good ones nowadays. The best thing to get peopple to add you is to just choose a sexy woman, put "im bored, who wants to chat?" as the header then comment videos, tons of ppl will add you, then in your about me put " put me in your to 8 and ill luv u forever", and let everyone else do the work for you.....your friends will put u on the top 8 because they pretend they know a sexy lady.... Easy!
the only decent mass commenter out at the minute is Jet Commenter, shutdown by myspace however if you email him he still sells lol.. ($200 odd tho..) never use mychanger, they steal your logins
