Yeah, I'd say linking all those accounts might prove to be of some value if they have or ever engage in something scammy (like bounty abuse, most likely).  But I'm not seeing where any of those members have cheated or anything like that, and I'm not sure publicly announcing the connection is going to do any good without some kind of smoking gun.

But man, if one person controls all those accounts--or even if it's a few people--I'd be willing to bet there's some sort of shenanigans somewhere.  Nobody collects that many accounts because they like to display them on their trophy shelf, ya know?
