Exactly! A massive double-spend attempt, going back to a time before they sold all their coins so they can sell the same ones all over again.

That's one way to think of it. Another way is people who had balances pre-chain restart are receiving a weird airdrop of a new coin. To me it depends on the meat of the coin... does it use the same QT wallet as the old coin or is it a new wallet forked from something else?
