Here’s an interesting comment from virgomonkey from over a year ago at http://en.forums.wordpress.com
And comment submission is still broken 😦
May 26, 2008, 12:07 AM Ok. I figured out the problem. These comments that aren’t going through are because they are being routed into the spam filters of those blogs we comment on. This is a recent issue. People are having problems commenting on my blog as well. I have to keep fetching them from my spam filter. They are innocuous comments. And it’s odd that the spam engine is calling these comments “spam” even though these comments don’t have any links or abusive text of any kind.I will forward this on to the support team in hopes that this issue will be resolved soon.
