Lol why so toxic with them? They are a good network with good offers, maybe his traffic isnt worth a dime. Every network has its flaws but dont call them shavers just because the traffic may not be as good. I was once a top 10 earner there so I know they dont shave, just the traffic can sometime suck. Fun fact when I tried to join lospollos and showed them my crak earning they didnt accept me. Now I still work with crak and some private networks that are invite only. People even said that chaturbate shaves, those guys paid me hundreds of $ back in the days, and my traffic was so bad, totally unworthy traffic.
His best aproach at this time would be split testing different networks and different offers, that way he can see what works and what doesnt, and if it doesnt work maybe he need to see what he is doing wrong.
