Increasingly, sites are using Instart Logic to block tracker blockers, aggressively preventing people from protecting themselves from tracking. See The Register article on Instart Logic.
Traits of this system are:
- Google ads served first-party from g00.domain.com
- All other required page resources (scripts for functionality, content images) are also served from g00.domain.com
- Using the browser’s developer tools often triggers the page to behave differently
- Hiding an element on the page using
display: nonecauses the page to occasionally load without CSS
We can’t currently work out a way to block this and protect people from the tracking scripts it hides. We’ll keep working on it, but if you visit a site that uses Instart Logic, we recommend you avoid it in the future until they stop trying to prevent you from protecting yourself.
