No matter how much traffic I send, they always have the same excuse: low-quality traffic on sight — it's a collusion with advertisers, just a scam! Don't waste your time! I've been working with them for three years and constantly observe this situation; they throw you a bone like a dog, while claiming the rest supposedly doesn't fit, but that's a lie. I've always tried to understand their benefit and concluded that it's indeed a collusion.
