That's pretty sad actually.
However, your post raised a point. Lots of people have lots of identities here; I've got 3 for a start. Looking down the list of members reveals an awful lot of members who have registered but NEVER posted, and even more (like my 3rd ID) who have posted once or twice.
Couldn't you super-moderator type chaps have a bit of a purge now and then, and delete members who have not posted for, say, a year from the list?
Maybe the 64 930 members are actually only 15. How will we ever know without a bit of action by the Mod's? Advertising revenue may suffer of course, but all in the name of truth and justice.
