In /r/privacy they started implementing the new social credit system where not only do you need karma, you need fresh karma, called a “Contributor Quantity Score.” So my usual aged, pop in every few months account with decent karma is effectively banned for being (actual term) “lowest value” because I’m not on Reddit commenting every day.
As for their plans, seems like a probability where they just want us to pay $5.99 a month to make the problem (they created) go away.
I used to use Power Delete Suite to nuke Reddit comments.
