Diggs, that's the number of spam messages in a single day! (The highest number on there is 8. I should have put the spaces in.)
I suppose I should do some actual analysis on it. I was thinking of plotting it on a graph. I suppose it's meaningless unless I compare it to the traffic flow rates on the site. It could just be that we were busy on a few days. It also gets in it's head that one post is spam and the person on the other end sometimes decides they are going to keep posting it until it gets through, which inflates the count. This count started when they started trying to tweek it to fix the false positives. Before that there were a lot of days when it got into double digits, but I don't have records for it. For comparison though, it's been in place for 2 or 3 years now and it has actually successfully caught... (wait for it) ...
3. Three. Tres. A grand total of three spam posts have actually made it into the spam filter since it went live.
Now, that said, before we did hand approval, and I think, more importantly, before Google changed their page-ranking system to disincentivize (my spellchecker says that's not a word but it doesn't like deincentivize either) we had a couple days when we would get one spammer dropping in excess of 200 spams in 15 minutes. Behold the power of cut and paste. I think the spam filter, on an active forum, has become a weapon without a cause.
