If you aren't going to accept the standard definitions of the words you use, the only thing you're effectively communicating is that you don't understand what you're talking about. Here's a thought: if PG-13 content registers as porn to you, stick to PG and below. Unless falsely accusing people of posting porn is your thing. In that case, I don't get it, but it's not my place to litigate other people's proclivities. As long as it doesn't veer into the legitimate TOS violation of harassment, knock yourself out.
