I signed up for the 1win affiliate program in 2023. Initially, I did not collect analytics on my side and completely relied on metrics in the partner account.

After a while, I connected the postbacks and started tracking the activity of the players in more detail. It turned out that I had one active player who was steadily generating income. At the same time, I cannot say that traffic was actively driving traffic in — perhaps this was the reason for the reduction in income.

One of the illustrative cases: the player registration postback came just a couple of minutes after my balance went into the red — after the loss of the main player. This was followed by a postback about the first deposit, but when the page was updated, the balance abruptly went into a significant negative. Later, the loss was slightly "adjusted", but he lost a little and withdrew. It was not possible to get detailed information on the lead — they referred to confidentiality.

I also noticed that the geo of the click on my side does not match the geo of the player according to the affiliate program. Perhaps this is due to the errors of the analytical service, but I cannot say for sure.There is a strong impression that with a decrease in traffic volume or an increase in profitability for individual players, attempts begin to "optimize" payments downwards. According to reviews from other webmasters, this can happen even with stable volumes.

The affiliate program is constantly manipulating and responding with something along the lines of: brother, more traffic fields and you'll have everything clear. Log requests are refused. 

Based on my personal experience, I cannot recommend this partner program for cooperation.
