If you don't mind my asking, how are the bots gaining access to the forum? would it be a simple fix like adding a "I Am not a robot" thing, or is there more to it than that?

They register, just like we do. They have an algorithm programmed into them, basically a set of commands that is (most probably) tailored for this site so that they are able to fill out the registration form properly. Since this is not very hard to do, most sites have some anti-bot measures such as reCAPTCHA (the "I am not a robot" thing you mentioned), but as the bot makers get smarter, so do the bots, so even that's not a guarantee to remain spam-free anymore.

I'm not sure how exactly Mahz plans to deal with this, but I have faith he'll cook up something nice. :D
