Shoot. Any ideas for potential solutions? I've tried form validations, character limitations, Akismet, and even honeypot fields, but it seems like any sort of spam filter needs a place to dump spam members like the form system has (but it doesn't). At this point, even something that blocks the spammers and doesn't put them into another "bucket" would suffice - I'm drowning in hundreds of spam accounts on my SQL server.
Were you able to find a solution for this?
One of my clients is receiving dozens of spam registrations and there doesn't appear to be a quick way to resolve it.
