I played on Westfall and it had 1000 followers (I assume that's bigger thing than likes?) and rising till the end. The server started dying and and the devs suddenly pulled the plug unannounced. They still had the 1000 followers for a month or so after that when they still had the website up. The FB profile was under the Dispersion brand with two WotLK realms who pulled the most followers, but those servers died at the same moment.
So this really isn't a indicator of anything.
And a friendly public service announcement: They launched again as "Grom Gaming Community" with fresh realms and cash shops and you know the deal. So if you have the wow-muchies while waiting for Kronos, avoid this scam.
