Spam Detection - Too Many False Positives

Sonny the support rep on my ticket requested I post this here.

The spam filter (Suspended Tickets system) catches a little over 1600 tickets/week for us, and we estimate only 10-15% are actual spam.

Feedback 1:  Please give us tools for more proactively training the spam filter.  Word & phrase whitelists + aggressiveness settings would be a start.

Feedback 2: Please allow us to turn it off entirely should we prefer.  I've done some searching and don't see any way to do this.
