What do you think of providing merit to those who correctly report spam/shill posts that serve no purpose?  I think this may end up helping the forum as a whole in the long run and could give some low levels a source of merit.  Of course, there is the risk of possibly over-reporting which would lead to mods opposing this as people are just reporting to try to get merit. 

I may have talked myself out of it, but I'm interested to see what others have to say about it.
