I've been watching Propellers for a long time, for several years, and I've tried many times to work with them in different roles - both as an advertiser and as a publisher. Each time the result was disappointing. I tried it this way and that way - I tried a lot of different verticals - nothing converts. Checked their traffic antibot system - about 50% of bots and one-pixel iframes.

But the most important thing is not even that. Many have the same situation, but not many allow themselves to directly steal the advertiser's money.

At one point when I try to access my account I see a message that it has been banned and there will be no refund of the rest of my deposit. In my attempts to find out what exactly happened - no answers, as usual at Propeller. They have an allegedly secret secret service called "Policy" (with a gasp!). This service decides the fate of small and insignificant creatures - advertisers, who like ants crawl around in the Propeller's expanse. This polisy has the exclusive right to decide when and from whom - without any explanation - to block your account, write off your money from your account - whatever you want at the moment. Since Propeller always has your money first, it's easy for them to do. And I repeat - no explanation at all. It's like a secret, but in fact - why not take advantage of someone else's money for the extra time. When they resell traffic - their profit is more or less 10%, when they block your account with all the rest - 100%. In the law it's called "Fraud" - theft of another's money by abuse of trust - you do trust them when you put money on deposit, right? That's just it...

Obviously, the entire business propeller (that's right, with a small letter, because I do not respect them at all) works on a few anchor customers (like World of tanks) and a constant turnover of newcomers. Newcomers come in, and either they themselves are wasting money, or here is how they are banned by the policy. In what proportion it happens - I do not know, but the fact that the withholding of money from bans accounts a significant part of the income - no doubt.
Now they will write in a response to the post something, as they wrote on all similar posts before me, some kind of formal replies, such as "our polisy never make mistakes. Do not believe it. They just came up with a very nice unobtrusive way of weaning your money - by bots, bans accounts with withholding deposits. Do not believe them. There are plenty of new highly effective projects on the market (I myself work with more than 20) - without these polices. Work better with them - there you will get a normal partnership attitude - here you'll be a "cash cow" without the right to vote.
