One of the major problems with Internet forums, or discussion groups are trolls. If the forum or discussion group is unmoderated trolling gets worst. If it is moderated and troll post are removed or edited the trools complain about putting a muzzle on their free speech.
Over moderating has problems, under moderating has problems. The one way for sure to stop a lot of the problem would be no handles, nicknames, or made up identifies. Everyone had to post under real name and no blind e-mails to register.
Than the problem would be boring forum content, the forum operator would loose money, as their daily visitor, daily post count would fall, thus less advertisers would want to advertise, and rates for banner ads would drop.
Mr. Emerson has to deal with trolls who want to just for fun trash his product, and then disappear after the trash is dumped. They in many cases have nothing better to do then try and disrupt forums, and Internet discussion groups.
I would think most REAL customer who have a problem, would pickup the telephone, or send an e-mail seeking resolution of a problem. Before taking a simple problem to an Internet forum like a pail of trash to dump on some poor business owner.
