In my opinion, you should take it as a gift - you joined that platform early enough and invested in it and now you can eat the fruits your tree bears - you will get rewarded hansomly enough while still maintaining quality content - there are a few examples in the list you added that don't upload shit - yes, they are rewarded hansomly but so are bitcoin or EOS early adopters - when the content is good people shouldn't fret too much about higher revenue, it's the way things are with early adopters.

I'm a nobody in SP aspects but - I'm not jealous of the quality content that gets great revenues, I just work hard and try to go up the ladder, and usually the top of that list that do make quality content are willing to help and upvote a quality comment handsomely.

Now - regarding the load that platform is putting on your shoulders - those are smart steps that you took, we have to remember the actual world and every day things like family and meals and meeting with friends and sports etc. There is an option of looking for the gems among the comments, they are usually longer or if they are short and witty, someone else might already voted them generously upon seeing them.
There is also cryptoctopus's method - he build himself a fan list of devoted quality commenters and he upvotes them automatically - it might not be personal like a manual upvote and a comment, but in time of stress it can help you reward your faithful commenters even without investing the time needed.
