And these 126 subscribers I think all (126 subscribers) got by the giveaway. I don't think s/he has received a single subscriber earlier. Note: right now the scammer has only 125 subscribers and soon it will decrease more. Few will stay live as few people will not check the thread and few people will not want to waste more time.
Funny thing is, I'm guessing the account he posted is one of his other "customers".
It might be an account is his others customer but I have checked before creating accusation there was no info about recent email or password changed.
My point was that in another thread he was offering 1k subscribers for $30 or something like that. Perhaps this is his plan to fulfill that request, and the YouTube account he linked isn't own by himself, but a customer.
