I concur with strumpfhos. Currently I have made ALL my photos private, so at least they can be viewed if I send them specifically. In the past these photos were NOT marked as X-rated, based on the comments and messages and views received, but they ALL had been recently marked as such. I, too, am not interested in providing free content viewable only by the paid members.
More than likely, I will soon just delete everything and not bother to visit the site at all, since it seems to be geared only toward the paying members.
I, for one, don't mind the ads on other sites that are more open to free members. In any case, there are a LOT of options available for those of us who just want to interact with like-minded individuals, and that do not cater solely to paid members.
