It appears (much like Trump) that his “employees” are working to undermine him. They always blame the “algorithm” but why would that ban people for re-posting content but not the original content creator?
IF it were an algorithm that banned right leaning people but not the original source that means there is some kind of social credit score built into the algorithm.
OR
This has nothing to do with the algorithm and its just another Twitter employee doing what they have done for the past decade.
I’m inclining to the latter option. I saw Elon react to that post with a question mark... he might have told his team to suppress it and they started suppressing all retweets of it neglecting to take down the original.
