Honestly Michael/bumface, you need to invite criticism, even trolling. It's needed to further develop the coin. Most of it is trash, but some of it is reasonable suggestions based on what the users of UTC have experienced. Trolls are best at pointing out problems or flaws. If you systemically moderate and delete posts all the time, you'd destroy any chance of meaningful thought and deliberations on how to make UTC better. It's simply a waste of your time and effort to moderate the trolling on this topic.
Please read this and take it in to consideration. You may not like what is being said about your cryptocurrency, but it is needed. I don't believe Satoshi Nakamoto moderated his forum when he created bitcoin or cared about what the critics said about it. When all is said and done, trolls are forgotten and whats left is where the cryptocurrency is at. Simply moderating the forums isn't going to change that, you're drawing more attention to the trolls and essentially "feeding the trolls."
