Sympathy for your loss. I dont understand downvotes much but am trying to follow whats going on. Seems like if a whale dislikes you they use HP to send your posts to never get seen land, or a dev can set a bot to track and auto downvote posts with key words.
Both actions are the opposite of free speech.
But downvoting your post smells of malice.
I hope #VYB helps, dont understand it, but the bit I did get sounds good.
RE: People who downvote a post with no comment about someone's dog that died with ONLY original photos.
