One cool thing about Lemmy, unlike Reddit, YouTube, Facebook, etc., is that downvotes (or the negative reaction equivalent) don’t force content upward into others’ feeds via an algorithm. Here, downvoting actually works to abate bad and upsetting content from being seen by more people. Engagement ≠ good content.
In my handwriting, my “v”s and my “u”s look very similar. I’ve not found any pair of words other than “value” and “valve” in which the word could one or the other if the “v” or “u” were ambiguous.
