You literally explain it in your next sentence, downvotes can be used for a lot more things than plagiarism and abuse.

I did read through most comments in this thread and the way you talk is pretty similar to Lucy, trying to use any word you can to make others bothering to explain to you the reason why they used their stake to downvote something against them and making it out as they're lying or trying to trick you. Basically being argumentative for the sake of being argumentative. Keep spending your time like this if you want your token to look like a bigger joke than the top earner's list of it.
