I think ultimately if downvote removing earnings could be removed that would help. Yet spam, and plagiarism should still need to be countered.

Ultimately whether someone DISLIKES a product or not should be irrelevant. When they walk into a store with their money they don't sit there putting black stickers on all the things they don't like. They simply spend their money on the things they WANT.

Everyone should be able to do that. Right now it has an anti-market mechanism of being able to make it look like demand doesn't exist simply due to the whims of the powerful.
