1 - For the most part, reviewers don't care what you're advertising & if the content matches that - they care that the content matches the category that you submitted too - so if you go & buy some teen cotnent to promote that site, you should have no problems.
2 - As far as content providers, you can't go wrong with:
Club Xstream
Adult Legal
And of course, post in the
I'm Looking For.... forum so that this thread does not turn into a
fest
(PS - I'll check the resources & see what's dead)
