Please everyone is push house Adnetwork a scam??

Want to start advertising with them but I'm really doubting,
-does it work really ?
-does anyone have some experience?
-do they have much traffic??( Usa)

these type of ad networks have a lot of bot traffic. Make sure you have a good tracking software so that you can blacklist such traffic and also, you need to burn money in beginning so that you can block most bot traffic
