Hey Dave1, thanks for those rules. I like to collect Apache rules... hehehehe.
You may try searching google... I haven't checked in awhile, but last time I went looking I found these rules to block bulk email collecting software.

I've commented out the Mozilla one, since it
could block, as far as I remember from the comments on the web page, any browser based on Mozilla that's created using some specific Visual Basic libraries. It was some seemingly low percentage of traffic, but I decided not to take a chance with it. I wish I could remember the page, but that was a while ago.
Also, people should check this thread out for more helpful ad-blocking discussion:
