When I had to do something in HTML, I went to a web-programming forum for help. One of the things programmed into it was that you couldn't post any links until you had several posts. If you tried, the post wouldn't get through and you'd get an error message. To fix that, all you had to do was uncheck the box that says "automatically parse links in text". Pretty simple. If you were legit, you'd just do it. But if it's a bot posting spam, it might completely screw it up to run into something like that, don't you think? Or have spammers already figured out a way to beat that defense?
