In the past 2 weeks I've been getting about 50+ new user/customer registrations on my site. They are all spam.
I can't find a setting to enable Captcha or any other way to put a stop to it (I did find one plug in that changed the URL but I don't trust it).
I don't understand why someone would create a bot for this, it's not like they are getting anything out of it, other than annoying me.
