While the 'Cat is an invaluable source for lyrics and factual information about music, it's also a great place to share opinions on musical and non-musical topics. As such, it's subject to the same set of Internet "social problems" that affect any other lightly moderated forum. The vast majority of people who post here are pretty well-behaved, but any forum that's not moderated with an iron fist is going to be plagued by a small minority of people who see anonimity as an opportunity to misbehave with few consequences. It's not anything unique to the Mudcat, and the benefits of being able to interact freely far outweigh the occasional desire to crawl through the screen and punch some jerk's lights out.
