I have recently (last 10-12 days) started getting spam comments on my blog. My blog is almost two years old. I realize, that spam comments are familiar, but have several questions here.
First, when I moderate a question as spam, what happens? Does it bounce back a request to the originating IP and thus confirm my address in any manner? I ask since the amount of spam has been snowballing. I went from 1-2 spam comments a week ago to 75+ in a half hour. (Fortunately, that load is not sustained.)
Second, why are the spammers able to post comments without registering a user. I require all first time posters to register and have their first post moderated. It seems that they can bypass this. Any help? I do have the latest update of WP and my provider updates the server OS and Apache on a fairly consistent basis.
Third, the spammers are only targeting two posts, one of which is quite old. Is their any good way to protect those two posts?
