The official White House position appears to be no support of the current bills in their current forms, but we do need to do something about piracy. - wwws.whitehouse.gov/petitions#/
As of the PBS News Hour tonight, it sounds like congress is shifting their attention to PROTECT-IP/PIPA, with some clauses related to DNS takedowns and targeting of U.S. domains cut from the bill. This is a substantially better position than we used to be in, but I'm not sure I'll trust the bill's contents until it is rewritten in the light of day rather than proposed by the media industry for a voice-vote out-of-session. Even without the worst clauses, and even requiring a court order for doing things like bumping sites off search engine results, my sense is that there have yet to be revisions in clauses which would make websites responsible for policing all user content in order to avoid being policed themselves. That would potentially mean that yes, if mods here didn't actively pull all content that someone could interpret as infringing (site content and forum content), and the gaming industry got a court on their side in saying that the core purpose of this site was to promote piracy-related activities, it could still be slashed pretty hard.
I would not object if the site goes black tomorrow. I don't suspect that it would have far-reaching consequences, but it would be a show of concern and solidarity.
Edit: and in case you aren't yet scared, or are mollified by the assurances that sites can police themselves and only those affiliated with non-US domains will be targeted, consider:
GMail is a service. Google operates international domains, and is thus a valid target for enforcement. If GMail polices all of its users' activity for signs of piracy in accordance with the law allowing them to indemnify themselves from legal action, that means... any and all privacy policies you have go out the window under that nice "unless required by law" clause, and Google gets to read all your mail and delete or report anything questionable.
A pirate ring operating offshore but using exclusively cheap US hosting is (at least according to the PBS interview) immune to PIPA because they have a US domain.
