I don't think the post specifies it has to be a technical problem. Besides, it's not a social-political problem until someone does the technical work. Does anyone have a proof-of-concept implementation for Firefox or Chromium yet? No.

it's a social problem, and the only way i believe we can ultimately solve it is by teaching everyone to be better people. until we do that there will always be people who will try to take advantage and become a bad actor.

teaching people to be better is the only way to avoid oppressive technical measures. because most technical measures will end up being oppresive at least for some minority or corner cases that don't fit the expectations.

i also fear that technical measures have a tendency to get in the way of diversity as they force the same behavior on everyone and punish or prevent people doing things differently.

...but mere education doesn't work (not against those who want to be a "bad actor") ... if anything, more education makes it possible for more people to be "bad actors"

you are right, mere STEM education could help enable bad actors. but children are not born wanting to be bad actors.

part of the education needs to be moral education, starting from childhood, about what is good and bad behavior. good rolemodels, etc. we will never completely eliminate bad behavior but we can reduce the likelihood of it occurring by teaching everyone about good behavior.
