Low spam report is Net positive for the forum isn't it? We may be moving to a free-spam Forum. I also had one of the lowest spam report in my section last month.
Unfortunately, there is as much spam as you want today, just look at what is happening in the Gambling board - according to my estimation, at least 25-30% of all posts in that board are pure spam. Members are less and less motivated to report anything, because it is a
"job" that is on a voluntary basis, and there are very few who want to do something without compensation.
