Let me take another crack at this issue.
If you post a bunch of pics, or even one pic, of a very hot guy in the gallery, they immediately attract attention. Everyone knows that.
If these pics don't seem to fit together, it calls your veracity into question. Not just whether the pics are really of you, but everything about you. You can be the nicest person in the world, and have the most erudite thoughts here -- but fake pics will make you a pariah here (to wit, Doublemeatwhopper).
So, if you have a random tattoo in one pic, a one-off hot cock shot in another and a pretty face in a third and none of them correspond to eachother, people will be attracted and ask for more. That's not being mean, it's not being a hater -- it's flattering. When the response comes back "I don't have any other pics," eyebrows get raised. You took only one pic ever of your cock?
Then, when that singular pic start popping up on other websites, it will deepen the questions, and call your own truthfulness into question. When you respond "I don't need to prove anything to anyone," it sounds like OJ pleading the fifth.
Enough of this nonsense accumulates into the whole site being a sham. So, I do care about it. If you can lie and deceive, I can care about its effect.
Oh, and one last thing -- if you claim to be 19 or 25, don't use cultural references of sitcoms from the 1960s. It kind of exposes your true age.
