Does anyone get any luck from the facebook wishlist program?

Tweet

Lately, I got a lot of invitation through message in mylot to join the facebook wishlist with paypal. Honestly, I already joined that program a couple of weeks ago, so no need to ask again. I didn't track it everyday how many people will sign under me though, because I don't hold such big hope that I will earn $100 that easy. Common sense, I want people join under me, and people also want me to join under them. Some held suspicious doubt; some simply already have their account registered already. So, I just want to know anyone have any luck to gain $100 already?
