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?
I'd rather agree with MarkM and marklin. There could be another way to think of it only if "revivors" would list NewBBQ under a new name and under a new exchange symbol, for example: BBQNew, a trading pair BQCN/BTC, or something like that. Without rewriting an old page of BQC on Coinmarketcap. Why not start their own page with a name NewBBQ?
In July, 2013 almost no one had altcoins, IIRC, there was a single altcoin exchange, Cryptsy, launched in 2013, also btc-e, but they traded a very limited number of coins (LTC,NMC,TRC...) Coins mostly were created to pump and sell them on Cryptsy. Devs left projects shortly after their launch, what tells us about their mentality. If it looks like an airdrop now, then it is an airdrop mostly to them and to relevant people. The same mentality could be seen now, with these activities again someone doesn't care about majority of holders. Remember that after original devs were abandoning their projects, other devs and community were dealing with abandoned projects - for years, trying to bring to life again and then to maintain them, sometimes not preventing projects from being dormant, but anyway their original blockchains exist and that matters.
It rather looks like a fraud because they have stolen all attributes of coin, also a part of its chain - for their project, and the fact they use a new wallet, which is not compatible with original chain after July 2013, doesn't make it look legitimate.
