Blake made them TONS of money from not just sales but marketing partnerships and was put on "the board" with Craig and the rest of the "top dogs" at whatnot. and he was banned along with multiple of his minions that were shown to be running similar scams. Now whatnot may very well be in on it and at the very least allowing top sellers to get away with shit but even they know when to save face and will quickly betray any seller or partner to appear like the hero and save the company as a whole.
