Are you saying you didn't fact check the content, but rather downvoted it because of low engagement?
Theres tons of posts on Hive with 10 to 20 usd in rewards with no engagement if you mean COMMENTS. Most people read things and don't comment on it. If something has 100k likes on youtube it might only have 200 to 500 comments for example. Same with reddit, twitter, etc.
I'm not sure what metric you are using to determine when a post is downvoted. Would you share what software you use to determine this?
