They shave quite a lot, and on average every two months they report that the domains are blocked and you need to change the worker file, otherwise your subscriptions go nowhere (to them, actually). At the same time, there isn't always an opportunity to quickly change the worker file, and sometimes there is no way to do it at all — as a result, you temporarily or permanently lose your traffic to another network (I won't specify), even if the domain gets blocked, the drop in subscriptions isn't that noticeable, but after such news, there is a sharp decline in subscriptions by 70-80%. I spent a long time adding subscriptions there, but the income doesn't grow, no matter how you look at it; with a similar partner program, the income is 5-6 times higher. I decided to test Clickstar because I saw an article about tests where the ad network showed decent results, but the shaving problem wasn't identified in the tests. I do not recommend it — it's better to work with older push ad networks — any of those that appeared among the first, they are more stable and reliable. For some reason, it's the domain of the worker file that gets banned; otherwise, you could link your own, but the situation with the worker is different, and that's how they found a loophole.
