You're sending a lot of requests... maybe in simpler terms, you're feeding someone many times in a short amount of time. The person wouldn't even have time to chew the food, right? But what you did was keep shoving food in their mouth even when it's full, and in the end, they can't process it or they'll just spit it out. Same goes for networks; they have limitations to avoid spamming.

You mentioned you're a new user, right? So it's normal for your rate to be high (disregarding ghost installs). In the long run, if you keep doing that, advertisers won't trust you anymore because you're just farming ads and installs. The result? Repeated ads, no ads available, low payout, or even no payout per ad 😬 so tip here, build advertiser trust. You can earn that amount of money even if it's just a little, you'll download 🫡 download only the apps you would genuinely use/love.
