The poster Koperic mentioned they were in Russia so I just assume they were Russians. Not hard to believe - Russians and Romanians are probably the biggest most prolific hackers on earth. So I expect to see more coins from them as they get better at scamming and making better and better ScamCoins.
I did not say they are Russians, I just posted a Russian translation of Shibecoin because the English version of that thread was deleted. TheDagger aka Alty I suspect is behind it all, hiring developers to launch coins as it seems he/she does not have the required coding skills.
