I decided to put a preroll from Clickadilla on one of my sites. There's not a lot of traffic - 70-80k visitors per day, mostly Yandex.
Plugged in through players their preroll and left it until the evening.

Started to ask the manager - he answered me:
"From your site there were 30k requests 28k impressions, overall 4k impressions were from our advertisers, 24k went through an auction to other networks, which showed prerolls"
I look at the statistics in the panel:
https://prnt.sc/obOKh9Be9Ylm there's 3.9k
I asked where are the other 24k displays?
The answer "Since there was no buyout, we gave the traffic to another advertisers by the lower price".
After all clarifications, he tells me: "What is sold to other networks, is not recorded in the statistics"🔥🔥
The following picture turns out to be, I sold them 28k displays, and in the office there are 3900 displays and earning is 0.91 $ (cpm 0.23 $) Where are the remaining 24k displays - vague answer. All in all, they stole it, as it turns out!
Here is a link to the entire correspondence: https://disk.yandex.ru/i/G-IPYKkQ60Rayw

P.S. They count on the nerds. He'll look at the statistics, there are 3900 impressions and the earning 0.9 $ and will think that that's because of the buyout. And there's not even a word about what they've resold..... I'm a little shocked that they are secretly stealing! 🤬<🔥
