I don't believe Tyrone asked any of the admins their opinion before posting that response. As we did not originally plan on using an offer provider, we didn't feel the need to correct it. After it being brought up again internally we have decided to give it a trial run to see how it fairs.
A lot of larger companies, such as Jagex already use this provider to monetize their own games. If an offer is asking for something you are uncomfortable answering or installing, you can simply not do it. If you find any suspicious ads feel free to report them.
As far as surveys go, I believe each survey has a specific target demographic they are targeting. And if you aren't in it, they aren't interested in your response. Unfortunately finding out if you are/aren't in it can sometimes be fairly time consuming. For the online game that you believe should have paid out, press the "Get Help" at the top of the page and contact support.
