I guess the only one who can prove that this is scam is those who participated on the staking. Had they already profited or did they get what the hex team promised?
It's hard to judge tho. Some articles are biased like they're being paid off to write. But this whole thing make the situation more controversial. Some says, it's Ponzi scheme and some it's an exit scam. Had the hex team really gone now? Or at least their founder?
Well, just a random thought.
