We can be pretty sure that @cxcrypto1 on Twitter was behind this.  There is still at least one post left on his Twitter account promoting the DogeToken airdrop.

I was also following the Telegram group, which was deleted at the same time as other accounts, and some of the things posted to that group were identical to some of the things posted to that Twitter account.  The guy in charge was also promoting a Crypto Accept airdrop and these physical coins or similar were promoted in the Telegram group before they were posted here:

I mean sure, he could be subject to a very calculated impersonator.

(I forget how many tokens were sold via the private sale, but I recall the price was $0.000495)

And...it was a scam, it seems.

No surprise.  But "dev" listed on Uniswap, rugged after only a few sales, claiming gas fees are too high for people and he was instead putting funds towards a CEX listing.

Then, the private sale at two times above the previous Uniswap price.

Now, everything is deleted, explanation is 'gas fees suck, token failed, but no worries b/c you can buy Dogecoin instead.' No talk of buy back.

Scammer is, btw:

Twitter links to his own bitcointalk thread, where he seeks a job, receives fake praise, and claims that scammers sometimes try to impersonate him. 

Dude's a scammer and not even a good one.  Could have made much better profit without necessarily even lying, given the recent Doge hype.
