Thanks for posting that link. That is very useful information and I learned a lot from reading it. I read the Yahoo! message boards sometimes and that place is just inundated with trolls. It's SO frustrating because every decent or normal coversation is just plagued with people who are there to cause trouble. I feel like I have a much better understanding for reading that article.
The freedom of speech argument is indeed one that I hear a lot. I post at two other message boards besides this one. One of them has a moderator but it takes a LOT to get action...the people on the board scream "freedom of speech" whenever the mod wants to take action on a thread. We see name calling, dirty pics being posted, and really mean and hurtful comments all the time. On the other board, the moderator is a bit extreme. A minor disagreement results on a thread being closed. The Dis board is a nice inbetween. I personally prefer some level of moderation...even if sometimes a thread closes prematurely. I cringe when I see some of the things people say to one another on that other board...like your article states, they don't seem to realize they are talking to real people who are going to get hurt.
Anyway, I very much appreciate that link and I'll be posting it elseware so other people can get that information.
Thank you!
