I am getting hammered on my blog with 200 - 300 comments a day which all seem to be bogus. I'm wondering if this is a brute force attack, and what I can do to stop it. The emails are very similar to this one- firstname.lastname@example.org. Randam letters and numbers with usually 6 digits in the (?)company, or website, name.
Does anyone have an idea on what I can do to eliminate these emails from being accepted? Thanks.
