Yeah, not all. But OP's site is packed with "traditional" F2P games that sell expendable resources to negate the effects of artificial progress delays or generally subpar free playing experience. No pain points = no sales. So the gameplay is rigged or screwed to create said points where none needed.
Fortnite is an exception. It pioneered the model of selling cosmetic and vanity items that have no direct effect on the gameplay. Good on them.
Similarly, New Destiny 2 is a repackaged shareware model - a demo for free with the full game for $. Again, it's a fair arrangement.
Not so with the pay-to-dominate and pay-to-accelerate games that OP's site is peddling.
I do absolutely agree with you regarding the game that sell expandable resources. Where you can earn coins in game normally but also purchase currency which progresses the game ever so further.
So many F2P games on mobile devices are like that and its crap.
They are however not the kind of games that makes people addicted, sleep deprived, getting in trouble in school or neglect family. The games that have worst consequences on people who don't manage them well are not free to play category. They tend to be big online games.
Unfortunately tracking the links is only way to keep everything free, without selling anything and without ads. All free-to-play games get featured regardless if I get commission or not. And no, F2P it's not really a plague, there is some great F2P games out there.
And that's without getting into the actual idea of promoting the worst type of games possible. F2P is an plague.
I can only guess that the commission on all these referral links pays well enough to not bother with any ethics.
