will say it again: the most effective way to curb far right agitators like Lowe, "Tommo" et. al. would be to stop their ability to earn money for it from social media or live streaming. So much of it is grifting for revenue, not attention.
Here's Rupert Lowe MP's payments from X Corp over the past year. This man is making serious cash from Musk's platform. Payments surged over the summer, during UK 'unrest', and when Musk was frantically re-sharing Lowe's posts... Bleak, lucrative work if you can get it.
