Shame you have chosen to focus on mine while disregarding the majority of the other hundreds/thousands that you also deem not worth the reward yet rarely act on them.

Pretty sure you are wrong about that. I don't seek out your posts at all, and don't even systematically downvote at all. Your posts are among those which I see with high payouts everyday and I may downvote if I happen to notice, but hardly unique in this, I downvote plenty of others too. But do keep in mind that we only get 2.5 free downvotes per day if voting at 100%, which I usually don't, more like 50% so perhaps 5 votes. The only way downvoting is to have a real impact is if a lot of people were doing it, which mostly isn't the case. A lot of crap still falls through the cracks every day due to there being hardly any downvotes overall, unfortunately.

so that the community can know what is "allowed".

Posting anything is allowed (unless you are violating some law or ToS of a UI you are using). You are just not guaranteed to earn rewards ever. That is up to stakeholder voters.
