They are useless full stop, response to violent video that inspired the Southport attack is to 'ask' or 'request' social media giants to remove them. Rather than constantly being nice to them, it is TIME we just TOLD them to remove the videos or face huge fines or maybe even being blocked from operating in the UK juristiction.
Then actually back up the threat with actual prosecution.
Along side that, the government could simply stop using these platforms and move to the fediverse, it would hit big tech were it hurts the most (profits)could encourage others to move here. Then IF and only IF things improve start to move back to big tech in the future, or maybe simply not at all.
