Oh my...
I have Moderator access to remove the pages and block the individual usernames, however I can't do anything to prevent people like this from registering and just posting again.
If someone has access to view the IPs they register with we could probably IP block this.
EDIT: Wow, I just looked at the history, this has been going on every day throughout July! Time to PM Brandon Martus. Maybe we can get some better security filters installed after this gets delt with too.
