Just out of curiosity; What is wrong with these people? they seem to be either spoilt 13-Year old's who talk tough but are wusses in real life or 40 year old child porn freaks. Personally i think its a combination of Low IQ and Unemployment. The only reason i looked at the site was because a friend said it was a good site. Needless to say; My respect for said friend has dropped considerably.
Seems like you've just been introduced to the internet.
When you mention 4chan and child pornography, I lol'd. First of all CP isn't allowed on ANY part of 4chan, if they do post it they're typically banned within a short amount of time. 12chan was the board based off of Child Pornography, which has been shutdown and now it's back up (I have no idea why).
Also, more than 90% of the posts there shouldn't be taken seriously because they aren't meant to be taken seriously. 4chan is complete shit now, there's hardly a thread that's slightly funny in /b/. It was alright three years ago, now it's just filled with shitter posts.
BTW, I don't visit any image boards regularly because of how bad they are now.
