Adrope and Qadabra ads are redirecting to worksathomejobs dot net. Snap : Are you guys also having same problem ?
I guess ad networks even don't know how this happens. It seems problem with ad system like yieldmanager.com
Qadabra is like a middleman between Big Ad networks and they earn a good shares from impression we send them. probably some big network has some advertisers who is willing to pay for such annoying ads. No official word from Qadabra yet !!
Even I was facing the same with Qadabra ads last week. Upon bringing them to their notice, they promptly removed that ad campaign from their inventory. All is well now.
advertiser may use redirect ads without acknowledgement from network. you should just report it to them.
