Is there any way to go into the CoH database and pull out the Top 100 sg lists for all the servers, there should also be a record of the person who registered the group. Or is that all data wiped? Should someone maybe ask NCSoft politely for the information since we are not asking for any sensitive parts of the game?
I know all of this is a longshot, I thought the questions themselves would be worth thinking about.
The servers are dead, so no. Well, maybe not "dead," but certainly not filled with CoH data anymore, if they are being used.
I'm not sure it's hugely relevant as to who started what SG at this point. Some SGs had their own websites, and could have stayed in touch that way, which means their founders are a known entity. Other SGs might be revived by their old founders, or someone who was a member, just to get the good ol' days of the SG back. But I don't think anyone is going to care about "proof" from the game (proof which doesn't exist anymore) - there's not much reason to impersonate the founder of an SG anyways.
