Personally and officially, I don't believe that allowing a place for something to be discussed is actively promoting that activity. Just as the cops and robbers TV shows don't mean that the networks are promoting the activities portrayed in that medium.
Personally I find "kill stories" entertaining. And as such taken with a grain of salt as well.
As for the reviews section, I'll be looking at that on my other site and make a determination then whether I think it would be fitting here (also pending further feedback on the idea from other members).
Thanks.
