Maybe you won $1000 Amazon bucks?
Wish I had an easy answer...mobile is THE target for spammers/scammers and rogue ads. They target selectively....ie: Iphone6 on Verizon network in south Texas from 7am until 7:30am. Then they stop and switch to Android phones using Chrome on TMobile 4G only in western Montana from 7:45 until 8:05. All this while using aosiurttt.biz or aosizrttt.biz or aositrttt.biz etc to push the garbage out (ie: dozens of different domains)
There are constant efforts by networks to battle this garbage...I (obviously) monitor it constantly....the new ads.txt initiative is supposed to help. Some additional tools have come up recently to battle it. Seems every time a solution works, a new scammer system develops.
A screenshot of your browser history should show the network and possibly the 2-3 redirects that were used to cause the issue you see. I can add those to the growing list of blocked domains. Occasionally, I can also determine the specific ad network involved and block them as well.
I'm on a SLACK group that updates this stuff regularly, anything they post I include in my block list. But it's never enough.
