So I got burned bad on a campaign, looked into the network and found some shady stuff. They kept showing low CVR but claiming high conversions and paying out for fake leads. Digging into their stats, I noticed weird spikes during off-peak hours, plus a bunch of leads that didn't match the target geo or behavior. They were hiding the real fraud behind cloaked links and fake referrer data. Used a simple traffic analysis tool, cross-checked lead details, and bam, caught them red-handed. Moral of the story: always verify traffic patterns and double-check lead data, some networks cheat like it's a sport. Volume over everything but not at the expense of trust.
