I don't think anything you do on a forum is going to elevate you to some "legendary" status, unless you manage to hack the board. Even then, people are just going to view you as some jerk, which is also the case with most things that will get you banned. The best you can do is be remembered for being an awesome spammer who's genuinely funny and going over the edge too many times. But even that's not going to make you a legend. It just means a few people who stick around for a long time will remember you fondly.
