Hi Alex,
Baiting can be a lot of fun, but you need to make sure you read and understand all of the safety information on 419eater. If you really believe that you would like to reply to scammers as a hobby, do follow the link Ralph posted, and start reading.
There's a danger if you reply using your real e-mail address, and associated information.
I'm also over at Eater, so if I can help you out in anyway, PM me (Same username).
