Some people use apps which hide posts they have interacted with. A downvote counts as interaction so people in turn then liberally downvote nearly everything. Yes it’s unhelpful and dumb. Solution, use kbin and at least you can see who downvoted you! (Except I don’t think downvotes are federated).
My main issue is I’m not shutting down my Pi-Hole, home assistant, NAS etc etc just to plug in something like this in, and then 24h or so later shut them all down again to retrieve it again. That said I basically have a collection of Pis (passively cooled and this silent) and a Synology disk station so the power use is pretty low.
