Here is a feature I'd like to see. I am constantly having "people" register to make comments on my site from the country of Russia (.ru address) as well as from the Chech Republic. But it is PLAIN these are just spammers and porn sellers. They often have names like email@example.com or firstname.lastname@example.org and the like.
So, I'd love a way to block the country code of an email address from being able to be registered in the comments registration section of my blog.
Is that possible?
