The forums are showing up on Google searches now. Didn't they used to not be indexed for web searches? Maybe the 150+ guests we keep getting are from web crawlers that have begun accessing the forums since the forums got upgraded. Although the upgrade was back in October, wasn't it? And the rush of guests seems to have started around New Years Eve.
A quick bit of Googling shows a number of posts promoting 7.X in the past week, including on Reddit and a number of other video and forum sites, so maybe we've just been Farked.
