Would be interesting to make a service where spammers have to do recaptcha-like spam flagging to get their account unlocked.
Is there any evidence of this? 1% bad content can mean that 1% of your users are bad actors, or it can mean that 100% of your users are bad actors 1% of the time (or anything in between.)
Even the best people we know have bad days. But you have probably also encountered people in your life who have consistent patterns of being selfish, destructive, toxic, or harmful.
This is not evidence that most bad acts are done by bad people. This is evidence that I've met people who've annoyed or harmed me at one or more points, and projected my personal annoyance into my fantasies of their internal states or of their essence. Their "badness" could literally have only consisted of the things that bothered me, and during the remaining 80% of the time (that I wasn't concerned with) they were tutoring orphans in math.
Somebody who is "bad" 100% of the time on twitter could be bad 0% of the time off twitter, and vice-versa. Other people's personalities aren't reactions to our values and feelings; they're as complex as you are.
As the OP says: our definitions of "badness" in this context are of commercial badness. Are they annoying our profitable users?
edit: and to add a bit - if you have a diverse userbase, you should expect them to annoy each other at a pretty high rate with absolutely no malice.
I believe that's GP's point! Any of us has the potential to be the bad actor in some discussion that gets us irrationally worked up. Maybe that chance is low for you or I, but it's never totally zero.
And even if the chance is zero for you or I specifically, there's no way for the site operators to a priori know that fact or to be able to predict which users will suddenly become bad actors and which discussions will trigger it.
But you likely aren't, and most people likely aren't either. That's the entire premise behind removing bad actors and spaces that allow bad actors to grow.
