Some accounts are deleting their posts after a few downvotes. It’s devastating on communities like c/asklemmy.
Lemmy doesn’t track an account’s karma like reddit. So, all downvotes will be isolated to your post or comment and won’t affect your account—unless you wrote something truly horrible.
Remember lemmy is a community effort. Deleting a post also removes all comments on it. So you are not only robbing the effort others put in, you are actively removing knowledge from the fediverse. Others won’t be able to find it through search and lemmy will seem lonelier than it already is.
They need to imagine for a second that there is no differnce between upvotes and downvotes. I make a anti commie statment in a crowd of tankies and those downvotes are validation of the truth for me. I see so many black and white hottakes online and getting downvotes for throwing a little nuance into their soured perceptions is honestly quite fun.
