I think they have proven that it works with thousands of YouTube videos with the same scam and basically the same operating mode (impersonating famous people). They have made quite a lot of money.
So they are probably on at least their second attack vector by now.
I mean, who knows, based on the massive number of imposter YouTube stream BTC giveaway scams, this might be a whole sub-industry in India by now. Similar to fake virus scams etc.
