Well I just made the upgrade to version 2.5.1 after no longer wanting to see that yellow tag on my admin. All in all I am happy with the new structure and style, (though I wish the login was a little more customizable). Anyway, I used to use version 2.3, and everything was fine. Though this installation works fine, I all of a sudden got flooded with spam comments.
What's more strange is they didn't comment on a actual post, but an uploaded image by using its permalink to get to a page where they can comment just on the image, (so you wouldn't see it unless you knew where to go). I installed WP-SpamFree and its been catching the comments, 51 so far that just keep commenting on the same image permalink post.
The comments themselves are nothing but links to other sites, they automatically got thrown into moderation before I installed WP-SpamFree, now they are just deleted.
Anyway, I'm wondering what I did that could have made this happen? Is this a bot attack or is someone trying to crash me? I used AskApache hardening plugin to secure my folders just to be safe. What should I do, or is this something that will pass?
