Advertisers sort your shit out
This is why people adblock.
If there must be advertising platforms and brokers, they should:
1. use simple text and images, no JS.
2. transfer the ads to be shown to the website showing them so the website is in control of serving them.
Because at the moment for a few quid anyone can fling any script which does anything at the browser and when there is malvertising it's impossible to trace.
