A recurring issue that makes life difficult for WGT users every day, like the quitters, will by necessity generate repetitive complaints from many site users, especially those who have joined WGT more recently. 
It would be unfair to deny Dave/isolater and others like him the right to voice his concern. If you remember, the last time WGT.com attempted to tackle the quitters issue, was in December 2009 – that's 10 months in which the resolution of the issue has seen no or little progress. Claiming that the issue doesn't exist, although it does, and telling people to shut up about the issue, won't make the issue go away. Quite on the contrary: it will keep generating even more repetitive feedback in future, because this site keeps growing, new users are joining every day, and most of them will be plagued by quitters sooner or later.
To sum it up: the only ways to reduce the redundancy connected to the quitters topic, are: 1) only permit the issue to be discussed in a single thread (merge any newly created quitters threads with the 1 already existing central quitters thread); 2) resolve the quitters issue itself by implementing reputation tracking. Once there's nothing left to complain about, we'll finally stop hearing about quitters every day.
