Unfortunately, BlahTherapy is the target of a team of spammers. Every measure taken to discourage their automatic bots is taken over by someone manually logging in and creating spam accounts, it really is quite ridiculous.
Short of having contact information to get ahold of them and saying "knock it off", there is very little we can do that does not affect the genuine user. The last-resort method would be to disable account creation, but that would stop new members entirely.
Until BlahTherapy acquires better security definitions, this will be a problem we must handle manually.
Please remain patient while we find a way to handle this severe issue.
