Some will still fall through the cracks...
Some spam will still fall through the cracks as I am targeting a very specific set of rules before my spam killer will delete the message. As a result, we still need our spam monitors to jump in from time to time to delete some of those spam posts but hopefully it's a lot fewer than before.
The other thing to point out is that my spam killer app won't stop you from getting a reply email message to your post... That's an automatic function of the board software when anyone submits a reply to your post. My software fires up every ten minutes to try to identify those posts and delete them after the fact...
