Can I go back and change the text of all of the down vote answers to the text of the zero or positive vote answers so that they identical lower vote answers will be marked as duplicate and not count against me?
Plenty of misconceptions here:
- answer votes are independent of the fate of the question. If the question gets closed as duplicate, all votes on the question and all answers remain the same. Only when the question (or individual answers) get deleted, then the reputation is affected accordingly.
- typically, votes express whether readers see content to be helpful and on topic.
- and most importantly, it seems weird that you have so much answer content that is worth duplicating. If you encounter a question that you already answered elsewhere, then the proper action is to vote for that question to be closed as duplicate, not to duplicate answer content.
Meaning: your favorite term unconventional is deeply subjective. You might consider your content to be out of the box thinking, but others might simply see it very differently. There can be many reasons why your "rewritten" answers see less downvotes. For example simply less viewers.
And finally: yes, what I can observe about you from the content here, that is unconventional. But not in a positive way. To a certain degree, you create the impression that you think you know better about the rules of this place than anybody else. And that isn't a helpful attitude.
I hope that I am wrong, but that is how it feels when reading your comments. If you always act in such ways, I am not at all surprised that many readers consider your content to be not helpful, and thus vote like they do.
