I highly doubt there can be any formalized process -- business or
technical that would ensure a membership 100% free of "bad actors".
And that's even before going into what "bad actors" are in your
opinion (vs. someone else's).
Rely on what the federation promises to provide you with, but nothing

It's not a good approach, agreed. Therfore it hasn't been recommended
(or actively discouraged) by/in this communtity for years.
(Never mind some federations still propagating a model where the fact
that some random company managed to sign an agreement to join the
federation is seen as sufficient to provide them with a wish list of
attributes to pick from, uncurated/unreviewedd by the federation
Again, only rely on those checks to be performed that the registrar /
federation operator promises to perform.

Not many federations have been pushing conent as the prime model for
attribute release for the reason above (and because of hard to
detect/control -- often contextual -- fringe cases where consent isn't
freely given and so would be invalid anyway).
In our own documenation it's mentioned as a last resort:
To me it's clearly the better alternative allowing the subject to
access desired services at their own risk (taking on responsibilty for
the attribute release via demonstratedly consenting to the release)
than for the organization to not release anything to anyone out of
fear of litigation (or whatever).

Others have, luckily. Entity categories (REFEDS R&S, GEANT CoCo for
those also having to deal with European cooperation partners) are one
of those things meant to enable scalable *and* controlled attribute

Sure. E.g. video2brain joined our federation, was later acquired by
lynda.com, which was later acquired by LinkedIn, which was later
acquired by Microsoft. It won't be a surprise to anyone here to hear
that federated logins do not work anymore.
(At which point they removed the multi-party federation capabilities
of the system I don't recall.)
