they can just disable somehow
There's no capacity presently to disable scripts or socks. The only tool Hive really has to discourage behaviours is DV's, and it's impossible to tell an autovote from a manual vote unless people using autovoters tell us they use them. The platform has dozens of mechanisms scripted in that add functionality to the chain, and anything we did that disabled autovoters would wreak havoc on all of them.
Oracles that enable identifying actual unique humans that Ned discussed before bailing might enable us to differentiate socks from 'mains', but that still wouldn't disable autovoters without disabling all sorts of useful and beneficial scripts, like ArcHive, all the various blockchain explorers, and the front ends themselves, as I understand it.
