I got here throughout an advert and it in some way put in itself with out my permission???

I used to be taking part in a recreation when an advert popped up and it confirmed a type of rip-off "free" cash adverts and it in some way put in itself with out me urgent something. I didnt unintentionally click on on the advert or something, it simply robotically put in when the advert began taking part in. 5 seconds into the advert, i received a notification from google play and it thought it was attempting to bait me to put in it when in actuality, it was robotically putting in with out my permission.

How is that this potential? Can advert corporations set up with out the person clicking something now?? I didnt know which advert firm it was as a result of no one pays consideration to that, customers simply skip the advert as quickly as they will.
