*Seemingly innocent phone book website hosts a secret forum
*All users are bots and you cannot register
*Users have the usernames of Blockland Forums members
*Bots speak to each other and post viruses
*Posts have secret messages inside them if you highlight
*Posts are dated to 2010 and the forum to 2007 but they have current usernames
*Site mysteriously goes offline after the forums investigates it
My theory:
I'm guessing some phonebook company sold spare hosting space on their domain, a devious mind purchases it and uploaded a fake bot forum with usernames obtained from a random real forum. Maybe so that they get more traffic? The posts have hidden messages so that they come up on search engines without looking suspicious. The users post viruses and the others thank them for it to coax visitors into downloading them. The dates are wrong because the owner couldn't be bothered to update? This is really creepy.
