Count to 1,000,000
I made this site for fun... What it does is allows you to post a comment with a website advertisement. It automatically adds a number to the count and displays your comment and ad. It also counts how many times that ad was posted in the last 3 hours and 24 hours so the ad posted the most is displayed at the top of the page. It uses ajax just for fun, I don't know if that will really help anything but I like it. Also, it autoblocks porn and bad language; every 100th, 1000th, 10000th, and 100000th post has a special display as a bonus to people who make those posts.
Does anyone see any errors, flaws, or bad things about it?
