I agree with your sentiment, but i don't think you need to have a heavy hand. Like you say, its a small group that are the problem. There are 4 guys just spreading constant negativity. They do it without facts, without knowledge or well thought out posts, and they do it over and over again on the same topics. How much does their traffic drive away those of us who like to be more positive?
People should always be allowed to make a point if they have a point to make. But constant negativity and railing on the program has no place. Moreover, there is a total lack of moderation with trolls from other sites that show up on recruit threads like this. Those posts wouldn't stay up for ten minutes on many other boards. Here I have to see troll posts basically encouraging recruits to go to other schools last for days. I don't mean to be critical, but it is certainly counterproductive toward what we (and the coaching staff) are trying to accomplish.
The reality is that Coach Ash and staff are going to be here for several years. Building some positivity around the program could help them get to the result they (and we) are trying to get to. Shitting all over the program every 2 seconds just so that you can vent and feel better is selfish, and does nothing for anyone but yourself.
