One of my regulars has emailed me to say he has had trouble trying to comment on my blog. He asked if he'd be banned.
I'll let you in on a secret: I don't have the power to ban anyone. I can delete comments to my heart's content (though I could count on one hand the number of comments I've ever actually deleted), but I can't stop them being posted.
So if you're struggling to post a comment, rest assured that it is not me exercising editorial discretion and deciding you're a prick who must be silenced. It could be your cookies settings, or it could be the software on the Blogger.com platform I use, or it could be a bug, or it could be... Hell, I don't know, I'm a Luddite when it comes to these things.
If you're having trouble with a comment that you really have to make (e.g. "God this is an awesome blog, you're so amazing at keeping it real" etc etc), email it to me and I'll post it, albeit under my name, but attributed to you. My email address is on the "About this Blog" tab.
