1. Introduction
The advertiser system in question appears to be a hybrid model that combines elements of traditional advertising and a lottery system.
2. How the system works
When an advertiser buys a banner ad, they pay a certain amount (10 RUB in this example). The website owner receives a portion of this amount (11 RUB, or 1.1 times the initial price).
3. Repurchasing the banner
If another advertiser wants to replace the existing banner, they must pay a higher price (1.2 times the initial price, or 12 RUB in this example). The website owner then receives a portion of this new amount (1.1 times the initial price, or 13.2 RUB for the second advertiser).
