John has some recent experience relocating, so FR is in reasonably good shape as far as this sort of potential threat goes.
The forbidden website went through a relocation that was fairly painful, took a couple months. Conservative Treehouse was booted a month a or so ago, and relocated. Went fairly smooth. Lots of work for a couple weeks behind the scenes (CTH got notice), and a week of so of pain making the move.
Pretty much whether or not a digital community survives is a function of will of the proprietor.
My sense is that FR is a small player at this moment in history. Might be good, for a change, to have a bit of obscurity.
HEAD TO THE CATACOMBS!
