Yesterday there was a question about solving the functional equation $f(\alpha t)f(\beta t)=C$ for $C$ constant, $\alpha^2+\beta^2=1$. It was closed as "unclear what you're asking" when the OP ignored multiple requests for an edit to clarify the implied quantifiers (for all $\alpha,\beta$? there exists $\alpha,\beta$''? etc.)
Today the question is gone but I do not find it listed under either "recently closed" or "recently deleted". I'm just curious how a question disappears without being visible in the "recently deleted" list.
