The previous comment didn’t ask for consensus for a social media or communication protocol specifically but rather was two steps ahead and was referring to the infrastructure that those protocols run on. Under the hood, there are various consensus mechanisms in current day social media or communication protocol infrastructure systems and those systems are needed to make sure (user) data is available. In order to run a data availability system, there’s a consensus required somewhere there. If you want to have the infrastructure provider run it “honestly”, in a protocol sense, then you need incentives for them to do so. If you need incentives, then you need kind of transactional system in a payment and accounting system sense. And that’s where you then need to care about “double spending”.
