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.
Up and down votes, no matter what their “intention” is, will have a different meaning for each person that uses them. There is no way to create a universal use for something so arbitrary. Someone will down vote, and the person downvoted will never know why (unless there is a comment of course). That is the nature of the feature. It’s not a flaw or a bug, it’s human. I know lemmy has a lot of tech nerds that are very logical (myself included) but we are still human
