There is so many fake ad networks being created lately. Don't be taken in by them! I'm not talking just about this forum, they are everywhere.
It's hard to spot sometimes because they have good looking websites.
Easiest way to find out:
1. WHOIS the domain. If they have any kind of privacy guard on the contacts, it's dodgy.
2. Does the website have a phone number? If no, dodgy.
3. Does the website have an address? If no, dodgy. If yes... check the address, is it real? Is it just a fake virtual office? If so, dodgy.
4. If a company claims to be US, check spelling, language, tone. You can normally tell if they are native English speakers or not. (This might not always be the case though). Also check if the company is even registered.
5. Check their social media accounts. This is where they usually slip up, maybe the admin of the page accidentally posts a picture to the feed and it just so happens they live the other side of the world from where they claim, according to their profile pictures and interests.
6. Terms and conditions, legally binding terms should always have a physical address. Any serious ad network is going to want to protect themselves. If the terms are not legal then they certainly don't care about you. If they do have an address in the terms, check it is not fake, sometimes they will even create a separate fake holding company website.
Don't waste your time, these networks have no plans to pay you anything in the long term. They are usually just using your apps to show their
AdMob account ads.
Just a couple of examples that I have seen on this forum:
