The four main woodturning forums: AAW forum, Wood Central, World of Woodturners, and Sawmill Creek require its members to use their real names. The top three reasons are to eliminate spammers, trolls, and those who behave as though they were raised by wolves. There were hundreds if not thousands of aforementioned bad actors that had been banned before the AAW forum instituted the rule requiring members to use their real names. Trying to keep up with those problems was a very time consuming job for the moderators. Additionally, flame wars and other uncivil behavior was all too prevalent when people could hide behind their anonymity. When the rule requiring members to use their real names was instituted, existing members were allowed to keep their "handles" if they wished. Since the rule change, problems associated with spammers and trolls decreased dramatically. Also, flame wars and other types of "problem child" behavior decreased significantly. The rule change didn't appear to have any adverse effects on forum participation and members were generally supportive of the change. Having moderator approval for new members does add a bit of upfront work for me, but it means much less work over the long run. Anyway, the bottom line is that there will be no returning to allowing anonymous members.
