Long ago I indirectly made $12.5k for a Steemit post, but sadly I think the platform has been trashed - I'm still watching it but this looks bad now...

I hear you... and there are a few stories like that around. I remember a couple of weeks following one particular hardfork in 2017 (I think?) every post I had made at least $50... and several made $200-250+ in the end, about $5K in 20 days... but you've been here a long time, too... so we've seen both sides of that coin.
Those sound like fun times.
But steem was worth 6dollars then (and bitcoin 20grand). It isn't to do with the hardforks it is to do with the market. I bet you are earning more now in STEEM than you were last year, it is just that STEEM is (currently) worth a lot less
Bitcoin peaked at $19k for a week and didn't go over $20k - I had a bet that it wouldn't go over $20k and was very glad I sold mine for $17k.
This is what I had earned on Steemit average per post seven months ago (It's a lot less now):
2016 - $19.35 with no bots
2017 - $10.01 with no bots
2018 - $12.57 with about 1/3 of my posts using bots
2019 - $3.19 all with bots and dropping like a stone
