The site could have just come out on the tubes and the scenes people were looking for were TeenCat's latest updates, so when they landed on his site, they saw the scenes were there and followed through with the purchase. Then as time went on, new updates were put up and suddenly the surfers weren't seeing those specific scenes that would have made them signup.

Could be a few other things, I'm just throwing situations I've seen before out in the wind. I have no clue how he promotes his stuff, so I could be completely wrong.... BUT, I still say his volume is too low to jump to any conclusions.
