Youtube again delete videos ?

Hi All.
Today I got emails from few friends that Youtube deleted their videos in last 4 days. Banned..use robots etc...
Youtube sent them email (same like sent to many people in december 2012)
Does anyone knows is Youtube make now again new action with delete videos with boost by mobile views ???
Seller who did views the claim that 100% facebook referrals. He is still sell and have rating 100% and still new positive feedbacks..
Videos were made in june 2013 and deleted 4 days ago and yesterday.
If somebody heard something please let us know..
Thanks

My youtube channel was also banned yesterday so maybe they are mass banning again.

That's why you should never mess with those guys on fiverr selling trash Mobile views. Exactly why I've never done anything with Mobile views.

Day by day I see more negative feedbacks on 5er under sellers who sell facebook referrals views...
It is not one shot action like was in december... now I see youtube delete videos step by step...

I got one of my video deleted too
