well there's one sure fire way to prevent yourself from being scammed. I've used this method many, many times and it seems to really work to keep these scammer guys from getting money from you.

They can't get it from you if you don't have it! If someone tries to scam me right now it would just be for practice. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
No seriously don't try this at home! BE AWARE!
