The other side of this coin sucks too: what if you are a pretty good writer or video maker but want to shitpost your way through communities for a day or a week? How embarrassing is it to see your one liner post earn 50$/HIVE? I believe autovotes can sometimes ruin some of the light-heartedness we need on Hive to really make this an engaging platform.
I think there are very few posts quite that extreme in having low value but high rewards.
It's more theoretical because I agree it doesn't happen that much - but we know some people easily get 20-30-50$/HIVE a post, and would get that too if that post only existed of the word 'test'. It would get downvoted maybe, and if it was a 'smart' oneliner from a consistent user it wouldn't even really matter I guess, but with the recent announcement of posting tweets to Hive it certainly might get interesting and subject of discussion.
