Wikipedia has fights and vandalism. If you look at the top of any page, there are a number of tabs. The Talk tab is for discussions of the content in the entry. View History is a computerized listing of all changes made to the entry. It's sort of a giant Undo list where changes can be reverted back to what they were originally. The person making the change is supposed to document the reason for the change, but most people making changes don't bother doing that. There are options for each change to see what the entry looked like before and after the change.

Looking at the Talk tab under Poser, somebody had to remove an addition that a user posted saying that a girl was a poser. There's a discussion about the validity of adding a link for Apollo Maximus. Somebody added a link for their web comic. A claim was made that 90% of illustrations with human figures are Poser. This section only documents the changes that somebody took the time to document. The discussions here aren't very heated, but Wikipedia also has articles on religion and politics and they sometimes have to be locked down till emotions run their course.

Any time a suggestion is made to give people more responsibilities, everybody ponders the worse that can happen. The worse abuse listed, if thread posters moderated their own threads, was that they would automatically block a set group of posters all the time. I don't see individual blocking of the most abrasive personalities an issue. Anybody getting blocked more than they like will have to eventually consider that maybe their posting style is too confrontational and they should change it. As far as having uniformity/conformity rules for posters to moderate their threads, I kind of accept that hundreds of people are going to do it hundreds of different ways, from zero post regulation to an overly control-freak level of thread moderation. The majority would fall into minimal interference with posts made. Too many rules is often more dangerous than too few.

An example of a site that has made itself nearly obsolete by having too many rules, visit the Open Directory Project.

Most people have never heard of it. Their goals are great: to create a human index of the content on the web, but their rules are so fastidious that they tend to drive out the editors that they sorely need to keep the site current. Considering the primary use of the site is by search engines, that value the human ranking or algorithmic ranking, the obsessive compulsive need to have very complicated rules for titles and descriptions became silly. I was surprised to see that the Poser entry now has an editor, but that editor hasn't done anything with the category in over a year. That means links are at least a year old, no new ones have been added in that time, and the Smith-Micro link for Poser isn't at the top of the page.
