Please define "ripping people off" unambiguously such that all those on the OP's list FACTUALLY qualify but Evan doesn't.
In
most scams you can say
a) What the scam is
b) What is the financial size of the scam
c) Who are the victims of the scam / Who got ripped off
d) How much did the victims lose
Except for ponzi/pyramid related schemes, in which case every scammer claims there are no victims.
