I challenge you to do this: next time you see a comment similar, go to the person's stats. Read their comments. I have recently noticed 2-3 users who have spoken strongly. I have noticed them posting in 1-2 threads. Namely the post season threads about numbers or proposed changes. I did not want to "out" them publicly. I did not see 50 posts contributed by them. I saw half a dozen or less from 2-3 people. Interestingly, I have noticed these people show up when similar threads come about, cry and spew shit, then return to their hole. You have been around here for awhile. I am thinking you have a decent read on most of the regulars here. There will always be a handful of guys who are Debbie Downers. Screw them.
My second thought: if someone says something you don't like, shoot them a PM and ask why or ask for clarification. If they are decent, I am guessing they will expand on it. You might not agree or you might find you were taking their comment too personally. Or they might just be a douchebag. Lol
Last option: use the ignore feature. I have used it. It has helped me. You cannot ignore a site owner though or admin. Trust me. It wouldn't let me block Jackalope lol
