I am located in Australia and I've found for the past few days (3-4) that I've been able to repeatedly watch the V11 Video offers (Olay videos) an absurd amount of times (over 100 payouts on a couple of these occasions).
As much as I'm happy to watch videos to support the site & gain cash, I suspect that this may be some kind of error and I'd have a lot more peace of mind knowing that it's been looked into.
I've heard issues of users being banned from V11 videos for abuse, so you may not want to watch them excessively. Its all something on the offer sponsor's end though, unfortunately.
