Pretty sad people will accept pay for an obvious ponzi like that. I was half temped to start dropping negatives on those people myself, but decided against it.
You should do that. Dropping negatives on those running the scams are of no use as the warnings are not seen by all those being affected by signature.
At minimum, crazyearner and legendster should get negatives. They are the biggest offenders in terms of impact.
It's true that they're untrustworthy by doing that, but dropping negatives for it is running a little too far into guilt by association - which is a well-known fallacy. We shouldn't start dropping negatives for things like that, especially those on DefaultTrust. Let's try to keep it a bit more sensible than that.
