Our system changed two days ago,and these changes seem to make videos get at least 100 to 150 views per day now doesnt seem allot but for now is okay.
keep in mind that same is happening with vagex it seems, i tested to upload two unlisted videos, one for u2bviews, and other for vagex, at the exact same time, 3 days passed, and both still freezed, althought the vagex one is starting to unfreeze yesterday (but still at the 300ish marker) and the u2bviews one is starting to unfreeze today.)
On insight stats exist a option to click and show "Unique users" and the graphic numbers are similar from u2bviews to vagex and vice versa.
I dont know if youtube updated their system or is still laging, i believe that they tried to update it from day 11 to 18 (when the whole mess happened on youtube), wich explains why views went crazy , they problably tried to update the system but failed, and now it seems good, althought i still think that there is no way they cant do to prevent this systems and views still coming wich is weird. So i still believe that they didnt updated their system to prevent this type of services but it is lagging, if you go to partner forums still exist people complaining about getting less views per day now, and btw, so you guys know, vagex is using
