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
Example (Karpeles):
a) "Losing" or stealing the money of investors and pretended to be hacked
b) 700k+ BTC / 700mn USD
c) People who had funds in his exchange
d) 700k+ BTC / 700mn USD collectively / individually 700k+ BTC divided by their respective deposits in cash or BTCs.
You can claim "scam" for any number of reasons but can't tell me (b), (c), (d).
