While very rare and unfortunate, it is possible to have responses to posts that are malicious, rude or abusive in nature. These folks are commonly known as discussion board "Trolls." I try not to "feed" the trolls with a response and if they persist, I report them to the moderators ASAP. I would encourage my fellow CAS City members to do the same so that thoughtful and serious discussion about our hobby can continue to take place on this site.
