I've been looking through mobile pin offers and see an array of differing rule sets depending on the offer / country. I'm trying to get a more clear picture of how these offers work exactly on the backend. I understand that different laws in the country may make things stricter etc, but really I'm wondering.
I'll try my best with answers here.
1. I'm not aware of pin submit offers that cater to certain OSs unless it's just part of the angle.
2. Simply for the fact the advertiser wants more leads. Usually incent will have a lower payout because the LTV of a customer will be lower.
3. A lot. It depends on the country. If they get enough complaints, their shortcode will get shut down (which is basically a database of their recurring revenue).
4. You need to find the sweet spot. Obviously you want people to be subscribed as long as possible. Depending on your pin country you could have freak subscribers back out to low $x,xxx. But a big chunk of people are going to always cancel after the first charge.
5. People tread the line differently. Some play it safe, some super aggressive.
Hope that helped!
