you are right - it doesn’t have to be one or the other… I just assume that for social media to work as I expect I don’t know most of the people on the platform. given that assumption and the lowering price of creating bots and ability to onboard them I expect that eventually most of the actors on the platform will end up being bots. people that write them are often insanely motivated (politically or financially) and creating barriers for them is not easy.
that is an interesting idea. still… you can create an account (or have a troll farm of such accounts) that will mainly be used to trust bots and when their reputation goes down you throw them away and create new ones. same as you would do with traditional troll accounts… you made it one step more complicated but since the cost of creating bot accounts is essentially zero it doesn’t help much.
