Don't worry, I'm still having fun on Hive and will continue to do so. The downvotes also have their justification.
Nevertheless, I would still say that downvotes on Hive are rather “unusual”. I don't know the statistics, but I would simply estimate that this is 99:1.
And I also find the comparison with YouTube somewhat difficult, as there are simply a lot more dislikes distributed here in general. (Are there still any dislikes on YouTube at all? I don't even know :D)
If you really must know, it's 0.245% 😊
Downvotes are primarily targetted for spammers and abusers, though sometimes there are collateral damage
