Re: How to control spam registration?
This is getting worse and worse. I just launched my first BuddyPress site and am getting spammer registrations although I have additional required profile fields and SI Captcha installed.
Sadly, the article mentioned (linked) above is not available anymore (I guess the spammers took down that site) and judging by the responses here there still seems to be no known solution to the spammer problem with WPMU/BuddyPress.
I spoke to someone on Twitter who confirmed that the spam problem started when activating BuddyPress – this would be in contradiction to remarks from Andy, I’m afraid. Anyhow: after reading comments here there seems to be a hole in the system somewhere.
(I guess the spammers have been clever enough not to spam testbp.org )
