Thinking fictional content is going to bring actual pedophiles is a reach and hilarious, [...]
Of course, they don't care much about the fictional content, but believing that it will not bring them is being naive and ignorant.
It works by waves. At first will come the loli addicts, the real one, not the joke that come here. They'll start to post, and if possible flood, their best content. Then will come the seasoned p*d*shit, the one that limits to fantasy, and you'll starts to see real content slowly appearing in between the fictional one posted by the loli addicts. This until the moment that real content will be more present than the virtual one. And it's when the last wave will appear...
It happened in the past, and will happen in the future. The adult scene, gaming and comics, already lost many sites because of this, just because the mods were too lax, until it was too late. And "too late" is not a way to speak, they are worse than crabs, once they stick around they'll never leave.
The last site was lost just one and half year ago, or something like that. It should be possible to find the thread talking about it somewhere in that section, or perhaps in Off Topic.
