I can only forward it to Google as we have obviously no control over every ad that is being displayed. I am on Android myself and I am not having this issue when I browse the site logged out from my account so i can't reproduce it.
We work around the clock to run this website so writing a post stating we don't care or don't do anything about stuff isn't true.
What you can try to do, but that will be hard on mobile is to find the source of the ad. But even then I can only forward it and report it as i have done before.
