Click Spamming

Click spammers fire clicks — from bots, click farms, or background mobile SDKs — hoping some land within the attribution window of players who were converting anyway. The fraudster’s click becomes the “last click,” and they collect commission for organic conversions.

Detection signals

Abnormal click-to-conversion ratios, conversions clustering at the extreme end of the attribution window, flat hourly click distributions (humans sleep; scripts don’t), and data-center IP concentrations. Programs that never audit these metrics are already paying spammers; the only question is how much.
