The question was asked:
And I think it's a legitimate question. Maybe he should have used the term "archival" tbetter be in compliant with US copyright law, but shouldn't these questions be allowed? There's (presumably) no illegal activity going on here?
Furthermore (should this be a different question?) If the question wouldn't be allowed, but isn't possible, is a "not possible" answer valid, or do we close? What if making backups is illegal, but the answer is "That's not physically possible" so we're not linking to illegal activity, is that allowed?
