Yes, but the dynamics may be different. If social network software is banned, and replaced with a ten million small DIY networks that don’t interact with each other, will that be any different than local pubs and clubs?

If the networks join up, letting people interact, enabling or encouraging hate between each other, there is an incentive for members of each group to report the illegal networks to the authorities to harm “the other lot”.

(This is just an off-the-cuff thought, I’m a long way from understanding sociopolitical dynamics)
