I did look into and will post a blog entry about it warning others to avoid these communities for now.

This is basically a denial of service attack by posting hundreds or thousands of new posts, making it impossible for others to participate in the community.

The forums will need to be shut down and the database scrubbed of all of these posts. Shouldn't take long, but it does require someone with technical expertise to do so.

I'm very sorry to see this happen...
