MSB people can be dicks. It's because people can be dicks. However it is nothing compared to WORA. Here you sort of wince if you are called out for something, but then everyone moves on. On WORA, if your name got mentioned, you all but cried. It was phrased in the most gut-wrenching manner that belittled everything about you just because they could. I would like to think we all grew up from those times, but there were definite mean girls with just being mean to be mean (sidenote: Mean boys too).
Some psycho got her panties in a bunch against me and flamed me a few times and people were all like whatever about it. So I didn't get the evils of WORA, but I watched it happen. I did try desperately to get on the worst purple prose description board. I think Cobalt posted one of my descs when she decided she hated that char. It wasn't that bad and peeps said so. It made me sad. So sad.
Here, it just depends what you are looking for. I like to see the bad side of games that I'm thinking of playing. You have to wade through the BS but you get a clear view. Mainly as I don't want to get invested and then find out -- oh these are the people that did XYZ. On the other hand, it can handicap people who have crossed the wrong people too. I would like to think we just call people out, but there are times that people go really on a personal attack here too.
So... I suppose it serves some purposes and is the same old thing in other ways.
