I see a similar thing on X (well, I would if I still used it) where my personal feed is very, very different from the curated 'for you' one.
many times you'll notice the new mod became active as a contributor on specific sub only 2-3 days before the OG mod gets banned and sub declared orphan.
Coincidence?
How can reddit even hand over a sub to someone who has nothing to do with a community? Simply because they install and control who controls the sub.
Mods get "comment/post removal" power, so they use it to shape the community towards specific "narrative", there is no audit trail for any mod specific actions unless you are a mod you perhaps can't see what all a mod is doing on a sub.
Also, they can simply make an automod/bot rule which simply removes your comment by creating a rule with your username after that you'll not know your comment is gone but others will not see it!
Conservative: we should do an atrocity
Leftist: no and why is this allowed on the platform?
Conservative: haaaa you can't ban me, it's free speech, cope or gtfo
Leftist: why am I on this platform full of idiots again *leaves*
Liberal: can't we just learn to get along?
