Sorry, but why wont younger people post in spam?
It'll be because your browser keeps the cookies, which contain your usernames, last visit etc.. so I presume they have a vBulletin addon that creates a new thread and notifies the moderators that you have signed up again. With a new IP and cleared cookies, it would be more difficult for them to find out who you are.
That is indeed how being co-owner works ;)
It happens.
The registration isn't really relevant, if a pedophile can view the PAPOY forum without registering then they probably won't register, however they won't register to view the PAPOY thread because they'd have to accidentally stumble across someone mentioning it, then again I doubt they'd even realize what PAPOY would mean. Hence the advantage to hiding it if you're worried about pedophiles :P
