It's not that I want to raise a particular ruckus, but I posted an answer to the question Does camera flash destroy art? on the Photo.SE site before it was migrated here. The answer received 23 upvotes before deletion, which indicates to me that it might, just might, have met some sort of minimum standard.
Is there something fundamentally wrong with the answer, or was it simply that I was not a member of this SE site? If it's a keep-it-in-the-community thing, I'll accept that as a valid reason -- these sites are, at least to a degree, based on a sort of verifiable level of trust that's reflected by reputation. If, on the other hand, there is a fundamental problem with the content of the answer, I'd like to know what it was.
