Think twice before using adsterra.com

Hi, just wanted to leave it here for someone considering them.

Gave them a chance for couple of days, saw low CPM and got back to my previous ads company. When the time came to pay they blocked my account, when I wrote to them they said that they received some complain about poor traffic from my site and going to investigate it (didn't received any news or money). With my previous ads company never had any complain about traffic and have better CPM, using them around two years on this same project. Just happy that I didn't used them longer, hope it will help to somebody, good luck.
