I've got approx 60 or so of those applications in my inbox since I started saving them (I keep them for future reference) and I'm pretty sure 95% of them are from the exact same guy (or group).
Maybe I'm getting cynical but I received this from "Bob" (webmaster@teenagevideo.net) :
"My name is Bob and I really would like to be your partner. I've
noticed that your site has great design and I hope that my galleries
will suit your TGP and I will get your partner account.
"
and I received this from "Jack" (webmaster@hardsexvideo.net):
"My name is Jack and I really would like to be your partner. I've
noticed that your site has great design and I hope that my galleries
will suit your TGP and I will get your partner account.
"
etc. etc. etc.
