I have had odd users registering for my site - using the META widget they can register - and several of them were emails attached to a website - in Asia. I don't know what they could be gaining from registering for my site - perhaps creating a way 'in' to mine my data? But I'm only a photographer with a website and blog - and a link to subscribe to my newsletter.
SO, I installed a plug-in that allowed me to custom-control the meta that was displayed, and removed the register and log-in. What shows now on the blog page is only RSS Post and RSS Comments. Yet, yesterday and today, I received new user registration messages. How is that happening? Is it from an 'old' page in browser history that they have? Does that even work that way? Confused - but definitely wanting to eliminate anyone from registering on my site.
