Here is the Reddit post, just to make sure that you got it.
"All right, here is a copy and paste from the developer of CoinUrl:
There are 2 banners registered in system (728x90 and 468x60) with a click price 0.0001 BTC, 17+12 clicks were registered, 14 of them were rejected by antifraud and money were returned. Other clicks are registered as normal, if you have complaints -- please, send IPs to support and we will return money for ALL fraud clicks.
There was no geo or language targeting set, the price was the lowest in our system, so these banners were shown only for unpopular countries like Indonesia, Vietnam, India. Mover, they were shown only on low-quality sites, because high-quality sites set minimal click price to 0.3-0.4 mBTC so this advertiser could not be shown there.
We recommend for our advertiser to stop such campaign, set geo targeting correctly and set higher click price.
In case of any fraud activity we recommend to send messages to support. Our company always return money to advertisers."
Oh I didn't notice the Reddit reply. Actually the ads weren't placed by my banners, my banner seemed to be ok, but those problem ad stats were from a investors who bought his own ad linked to his referral link.
