Re: Isn't it ALL a BuddyPress issue?
Well… with regards to SPAM… I’m not certain… but I suspect that’s actually BuddyPress-related. I’ve never had that issue on any of my other WordPress sites. But my BuddyPress sites are rife with SPAM signups. No matter what I do it seems. The only solution I found (after trying literally everything I could find here and at wpmu) was to block all proxy methods.
