i paid the most.com

Is this for real? People pay for this?
Yes they do. Unless nobody has yet, in which case, no, no they don't.
How long will my message be on the front page?
Until someone else decides to pay more than you. No shorter, no longer.
Ha hah, I'm going to write something awful and racist and shitty!
One, that's not a question. Two, fine, but I'm going to change it and probably your name afterwards. Why? Because I can do that and I have no respect for idiots.
