Popads vs PropellerAds - Which is better for beginner?

Definitely PropellerAds for a beginner. PopAds is cheap and has huge raw volume, but it’s plagued with bot traffic unless you have massive blacklists and a solid tracker (like Voluum or RedTrack) dialed in. PropellerAds has much better built-in fraud filtering, responsive support, and their Push/In-Page Push formats are far more beginner-friendly than pure Popunder.
