Their "websites" are non-existant, or at least just don't answer. Could it be they will work later on ... and have bad stuff?
I got their email addresses. Are they genuine or fake? I bet fake.
The words they post are generic (except one that made reference to something not in my blog). So I wonder how they benefit. If I were to approve them, would that let then bypass their way in the next time using the same email, even if the email is fake?
I do know genuine, logged in, WordPress or Gravatar users are able to be approved once (from the Pending queue) and subsequent comments go right in. I'm just trying to get an idea what Akismet is accomplishing, here, and what I might need to be on the lookout for. I do work in network security, but I have not dealt with comment spam before, so I am curious.
