Well, personally, I dont see the purpose of up/down voting at all. If a post is offensive or inaccurate, it can be reported to a mod to take appropriate action. Up/down votes just allow someone with an axe to grind to discredit other posters without any reasonable basis.They've downvoted me several times in tech areas over the years.
They've been here since 2019, and that's all they do. I just learned to ignore them because they've never posted anything in close to three years here. They pop in here every 2-3 weeks, downvote answers or react to other people's posts, and leave until they come back to do it again.
It's annoying for sure, but there's not too many users here who just downvote and don't at least post something (at least occasionally).
