A family type blog I host has begun to get a lot of new registrations and they are obviously not interested in my blog, they are coming from .ru addressess and have names like cheapmeds.com. So two questions.
What is the logic of registering on a site if you are not going to use it to spam - all these guys are doing is registering. Is it purely for the backlinks they get or is there some more dangerous reason?
Secondly, what's your recommondation as regards a captcha plugin for new registrations. I think I'm going to have to instal one of these.
Many thanks for any advice
