Unfortunately, Jordan, you've only received part of the story here. Several of the posters who complained the loudest have, in turn, aggressively pursued both posters they believed to be "returnees" as well as any poster who deviated from the "company line", so to speak. In at least one instance, a well known poster has assumed a new alias (using a former poster's handle), as well as creating a new posting name with an offshoot of a targeted poster's name, all in an effort to chase that poster off. He and other posters come at people with whom they disagree aggressively, and they've been called out by several other posters who are tired of their conduct. They regularly engage in the behavior they criticize (name calling, predominantly), and they offer little in the way of actual meaningful contribution here.
This is your board and you're welcome to do as you choose, but several of the most prominent complainers are also some of the board's most well known instigators, and the board suffers as a result.
