I haven't seen this behavior out in the wild much, but it happened again recently and I was wondering if a flag could be automatically raised when this happens:
- User posts answer
- Answer is down voted
- User deletes answer
- User posts exact same text as a new answer
- User effectively ditched down votes
- Got down voted again? Wash, rinse and repeat.
- Profit (perhaps after modifying the post, which is what you should have done to begin with)
I feel that this should raise a duplicate content flag, with slightly stronger wording. Would this be possible to implement? Or, perhaps, don't let users post new answers if they have a deleted answer to a question. Rather, force them to edit and restore the deleted answer instead, unless locked by a moderator.
I do have a link, but I don't want a lot of people to descend on it and create an even bigger disruption. It happened exactly as I described.
