This is the Internet. Security can help, but it can be costly. Even then, some hackers are skilled enough to bypass it. I don't think most would care about a site like this, though.

I don't know what DocJohn will do about this, if anything, but he or whomever handles the website and/or the boards will need to get familiar with security software, if he's/they aren't already. Ideally, he'll get more than one form of security.
