I have a number of fraudulent members signing up on my site as free members. Is there any way to present that?

@donnaamos
Are they typing nonsense into your registration fields and using email addresses that can’t possibly work, and then not doing anything at all on the site?

If so, I believe am also having this problem. I was actually just coming to ask what would be the best method to prevent such users from signing up.

[@donnaamos Member 13 years, 12 months ago]

Yes, but some are starting blogs that are not quality content. I need to stop this some how. But as you see I ask the question 2 weeks ago and no reply.

Anyone have any ideas on this? I know that BuddyPress is having issues and all, but this seems to be becoming a problem for some people.

Know that when you open up your registration for anyone on single WP or WP multisite, whether you have BuddyPress or not, you will get spammers and sploggers. Only “closed” or by-invitation-only sites have escaped this curse completely.

There have been different solutions using plugins and techniques to prevent this but these bots and humans spammers/sploggers are relentless. Search online and you’ll get many answers/methods
