Try to understand that we are at the same point. Maybe, (as far as I remember) we can "interpret" abuse, inside the old situation, when some countries had 100 daily videos, and we had managers obtaining +50 per day, despite be "legit offers" but "be a abuse", and some managers took advantage using vpn too, to have access to these 100 daily boosters that were not available in their countries.
This years ago, that is when rules were made, so was illegal the "abuse" considering that if you had 100 daily offers was not fair watch maybe 50 videos. Of course the countries that had no videos and used vpn to have access to these offers were doing something against the rules.
Then, actually, to prevent the abuse that we had, the videos were reduced (despite that the amount of videos depend of the zone), so with the "limit", the "actual limit" that is around 30 videos daily, this is legit.
So, I keep my version again (waiting for some more specific clarification that to define the situation would be great^^) and I say again, that "legit" is what you can obtain actually in your country using fair methods.
So the only way to cheat or abuse actually -as far as I know- is using vpn (here why is related and associated despite that you won't xD) to have access to countries with higher amount of videos/offers than the one where you live.
Despite all I will try to bring here a more exact answer to enlighten all us and make us reach the divine knowledge.
