Short update,
As of late I've been working on a system to ban the IPs of scammers, and ironing out a few bugs in the process. After that I plan on working out a way to have little country flags next to the posts, corresponding to the poster's logged IP.
If somebody is flagged a scammer, not only will they get a mean IP ban but they will also have that IP and their email posted on a webpage of known scammers. I doubt there will be much scamming going on though, as most people aren't mean spirited.
