The enemy is continually infiltrating, Breitbart went through similar a couple of years ago - they obviously tightened up quality control, as I have not seen a slimey leftists authoring under their banner for a while.

I suspect X is suffering somewhat similar - Elon just needs to keep rooting them out, and maybe have his AI programmed to do quality control - to support the truth, not the alliance of evils narrative, and, removing patriots from the battlefield.
