I have encountered similar projects before, and my opinion about them is mixed. From the perspective of an advertising network, I see downsides, but from the perspective of earning money, there are upsides. The essence is as follows: as an advertiser, you place ads in the browsers of other users. In other advertising networks, webmasters with a warmed-up audience place ads on their resources, which increases the likelihood of purchases. Here, the network simply offers ads to those who want to earn money by viewing them. Think about how interested such an audience will be. The people who see these ads (by the way, there are targeting settings by gender and geo) earn a small amount of money for viewing them. It's not much, but still better than nothing. Moreover, no one is forced to watch the banners, so the income comes in naturally, which is not bad. Therefore, I have a positive attitude towards this service. I wouldn't order ad placements here — it's a pure waste of budget. I used to have a plugin that paid for views, and I earned a couple of rubles a day. In my opinion, it's not worth the effort spent, not even enough for internet costs. But perhaps for someone, even these small amounts will be sufficient, as there is income, payments are made — the service fulfills its obligations.
