I was using Adsterra as a secondary advertiser for banners. Family friendly web site launching +20k of their ads daily.
After sometime, they started to inject redirects in its ads.
I complained. They removed the redirects but few days later I was quicked out from the network claming my trafic was low quality.
All my traffic is from Europe and the USA.
Nevermind, good riddance. Their ads are shitty and the payout is ridiculously low. Some times $0.01 for those +20k impressions.
Looking for another secondary ad network now.
