I was wondering if anyone had any solid advice for stopping spam signups to a wordpress site?
The type of site is a classified listing theme (it's BristolBedandBreakfast.net) and the amount of spam signups is ridiculous. People (bots) are signing up with the hopes that they can post an ad listing on the site with a link... only it's pointless on my sites because you need to make a payment to make the listing live.
But the spammers don't know this, so accounts are being created anyway. It's not a problem in that they do any damage, but the main problem is that every time a spammer signs up, I receive an email notification. When you have a lot of these sites and a lot of spammers signing up to each of them... the amount of incoming email is enough to bring your server down, never mind the inconvenience!
I've used advice found on support forums for the theme I'm using, but spam is still a problem.
Recaptcha is as good as useless as software can just solve the codes pretty easily.
Does anyone have any recommendations?
