Speaking with my docs.rs hat, and having dealt with abuse situations like this in the past, I'm wary having an RFC specifying what the docs.rs team has to do in case of abuse. We can't foresee any possible abuse that could happen and what the best way to address it is, and tying the docs.rs team's hands in those cases would likely worsen the situation, not improve it.
By the way, the crates.io team is completely separate from the docs.rs team (the only membership overlap is me, as I'm in both teams), both in a decision-making and in an operational point of view. There isn't anyone on pagerduty for docs.rs at the moment.
