Why was this question about usage of twofold/threefold deleted?
No explanation is given. I find it hard to imagine this one is General Reference, when I compare it to countless other really trivial questions that don't get deleted.
This seems to be exactly the kind of question we do want. It asks about grammar and the answers involve discussions of semantics, usage, and definitions.
The question was plagiarized from another online forum. Based on this user's previous behavior, deletion was the appropriate course of action. The question itself is not necessarily close-worthy, which is why I didn't close it before deleting.
