I really fail to see how she is scamming anyone. She is being paid to advertise a product and everyone knows it. I am not a huge fan of alt-coins in general but do not see how dark/dash is any different than the rest of them. Some are pre-mined, some get insta-mined, some get ICOs...they are all the same...cash grabs.
I have no problems with Amanda B Johnson getting paid to promote products, in fact I think Dash is one of the few decent altcoin projects,
my problem is when she started hating on bitcoin core and the blockstream developments, and then she started shilling bitcoin classic as a lot of people know. Getting paid to attack other projects is what I don't like, specially when it's crap like XT/Classic/BU or whatever is next.
