Ok after I was looking through my comments I noticed a few people that must have it in for me. Because they posted with my username Qwerty_ on the review of James Gill’s blog.
The things were not posted by me you can tell as it is not even a link in the username. Check the comments out at the post.
My questions is can I disable the username Qwerty_, Qwerty etc so people cannot comment with this user name? so future things like this will not take place.
Thanks for your help. James I hope the comments did not offend you or anyone else and again they were not made by me.
[Update]
Yes you are able to block user names as well as e-mails from within wordpress, you can do so within the options-> discussion menu. Picture below.
I have blacklisted the user names Qwerty_, Qwerty and Q@the1qwerty.com so hopefully this problem will not take place again, blacklisting them automatically sends them to Akismet classified as spam.

Discussion menu is where you need to go in options.

Add you blacklistings in there.
Hope that helps everyone out.
