That's an interesting point. I mostly answer in Python, HTML, and CSS, and haven't seen this happen over there.

It reminds me of when SO added the feature to make front-end code snippets in answers runnable. Perhaps an evolution of that is to provide the equivalent for backend code. Do you think this would solve the voting problem you described?

To the linked question - Do you know if it's possible to undo a "mark as dupe"?

It is possible to reopen, but it requires 5 voters with >3k rep to do so, or one voter with a gold badge for the tag.
