I challenged the view figures with outbrain or two reasons
1) one the number of people they said didnt watch over 30 seconds on my views didn't match(in any way) normal conversions.
And 2) more critcally YouTube removing a large number of those views. I can't prove they were not genuine but YouTube are normally pretty good at spotting this kind of thing.
The customer service has been shocking and they took full payment in the middle of the dicussions before responding - I would avoid them.
