The million dollar question here is how did he present himself on the site prior to the Mexico site? Specifically his age.
I presume that as a 14-15 year old camop he would have operated his site as non-nude, and then done private webcam work under the table for men who solicited him for it. Being that such a site would have appeared clean inside and out, there would have been no reason for him to lie about his age at the time.
I can't see a young teen getting away with running a full blown porn site and getting away with it on the only traffic source at the time, webcam toplists such as Jasbits.com. Plus news stories have stated that some men paid big bucks to watch him, and that wouldn't have been the case if he were running a regular porn site.
So going with the theory that he went by his true age early on, that creates problems for some members of the Mexico site. How many remembered him as the 15yo who had the clean webcam site a year earlier who now suddenly has a porn site?
What if they can link members of the Mexico site to the previous site? Doesn't that prove they knew his true age?
