Let's make something abundantly clear.
If you don't like how something is being run, you don't like the people in charge, and you've all but exhausted your opinions on the matter, there's absolutely no use in continuing to pound away at your keyboards assuming that anything's going to change once your arguments have been presented.
At this point, you have a few options: displace yourself from the situation (in the case of Petri, Arcbell, and the inescapably moronic administrators who let them have any sort of position of power in the first place, this would mean logging out and taking a break for a bit), suck it up and learn to deal with it, or continue to waste your time fighting it.
If you choose to waste your time, that's on you. If you choose to displace yourself and find something better to do, even better. If you choose to suck it up and learn to deal with it, well, that's complicated.
No one is forcing you to use this website. Going on a crusade against a single pedophile moderating a niche mafia website isn't some noble cause that deems itself worthy of the time and effort you're putting in to it. If pedophiles you off and creep you out that much, there's about 8 million other better causes to dedicate your time and effort to.
That being said, I'm just going to log off for a bit until things blow over. I personally won't log back in and use the site until something changes. It's of my opinion that it's in your best interest to do the same - especially if you're not 18 yet, or if you value your privacy and your personal information.
