About six months ago, we were hit with a serious rash of spam and had over 20,000 comments posted in the span of about two weeks. Unfortunately, at that time, we had no spam moderation tools installed in our blogging platform. The comment spam overwhelmed our ability to deal with real comments.
Today, we deleted 37,000 comments that were pending moderation. we are quite certain that ten or eleven of them were legitimate, and we apologize to anyone caught in the fray.
