I'm a blog reader, not a blogger. While logged into my WordPress account, and I post comments on a blog, I am consistently identified as a spammer and my submissions are sent to a queue to be approved by the blogger. I'm the only one of his readers who experiences this situation.
The blogger has tried to greenlight me time and time again, but is helpless to figure out why your spam detection system won't let me through. Is it really true that WordPress bloggers cannot greenlight an authenticated (logged in) user so that his comments are always accepted? I have yet to have a single comment accepted without waiting for the blogger to approve it. I have no reason to believe I've offended the blogger, so I trust he's not doing this to me intentionally. He approves everything I write.
