I don’t read r/conservative much but what I’ve seen is they keep banning actual conservatives because they correctly call out what Trump is doing on things where it’s not about left and right but right and wrong.
Some people are saying that it could be coincidental. OP asks why would the two accounts who post so regularly just happen to both stop at the same time on that day.
That ideological diversity did not just fade on its own. Over the past decade it has been actively pruned away. Spaces like r/conservative now routinely permaban anyone who steps outside an approved line, including the kind of libertarian arguments that used to be common. What remains is a tightly controlled echo chamber that presents itself as grassroots discussion while functioning more like propaganda. Given that shift, it is hard to take it seriously as a place for real conservative debate.
