To echo what others have said, this poll is meaningless without a definition of altered. People then fall on a spectrum of how far they deem something to be acceptable, and won't be captured by 2 or 3 poll responses. Personally, I couldn't care less if a card I buy formerly had a stain on it. I see it as no different than someone wiping away some dirt on a vintage car they're trying to sell. But if that car had a part that was replaced without disclosing it (or a card that had color added to it without disclosure), that's a problem.
