Keep in mind when asking me that question that I probably have a different idea than you of what "children safety" means (for example: we probably believe different reasons for why it's best for all concerned if pedophiles avoid breaking the law). But for nearly all definitions, you'd rather have us acting as we'd like to envision ourselves than acting as society envisions us, and having a community enables the creation of that self image and sense of what it means to be ethical. We're not going to go away, and we're far more numerous than most realize, so you might as well let us figure out how to be good people. That can only happen through dialogue, and for the time being that dialogue is only possible anonymously.

Also, it may sound self serving of me to say this, but the risk of pedophiles on the Internet is waaaay overblown. The behavior most of society considers sexual abuse is far more likely to be from a child's caretakers than some stranger on the Internet. And child pornography, from what I understand (and I really am not stupid enough to download it myself, even with Tor), is mostly the same old images again and again.
