GiantITP.com is NOWHERE near the quota of disk space allotted to them, and the user profiles represent a small percentage of that space.

Unused user profiles only cause slowdowns when it comes to looking at the Member lists, and not that much of a slow down, yet. Otherwise, it doesn't really impact the performance of the Board, the way it's designed.

So, there's no real value added by removing the old users, and gives us the ability to say "Hey, friend, welcome back, we missed you" should some return. Not to mention the possibility of alienating lurkers that like to read, but not post.
