You're just making stuff up show me these accounts and the change in the behavior.
Nothing is going to change these bots are already programmed and there's no reason to change them to do the kind of stupid shit you're assuming they will. There are still bots that vote at the 5 minute mark from 5 years ago. Change is slow. No one is being incentivized to do less work than they were already doing. Doing the work was always optional.
