Wish sites

I decided to see if there wish granting websites to see what kind of thing they offered and was it done in a serious manner or in a similar way to my project with people just saying what they want. I stumbled across this rather interestingly designed website.

They claim to be able to grant you a wish but I was looking for the catch and it seems to require you emailing a link to 8 people thus spamming and chainmail comes into it. It's interesting to see people actually using this site or at least claiming to be.

I wondered if anyone i knew or anyone who's submitted to my own project would try here or believe it. Personally it looks like an obvious scam to promote their site and should your wish come true it'll be entirely coincidental, but obviously not everyone will believe that.
