I have been recently looking into 'edit reviews' that I have voted on and voting didn't go unanimously.
Where I have discovered a few cases where code sections were deleted or changed in a ways that would give different meaning to question (basically vandalized), and they were voted 2-3 and (thank God) got rejected, but it was a close call. Which would imply that there are cases when questions are being vandalized and approved. I am not sure how much development effort would this require (would it be cost efficient), but I believe that I would add some additional protection if 'suggested edits' that have edits in code section, and have non white text changes:
- Would be reviewed by more members (10 instead of 5).
- OR members with higher rep (lets say 10k+).
- OR those that never have been banned (or failed an audit).
