As a publisher with a significant number of ad requests monthly this would be a godsend. I just spent the last week tracking down ads that were maliciously redirecting my mobile traffic off my site.

Turns out it was coming from a network called Sovrn, which is ironically a member of betterads.org and apparently "recently added an extra layer of protection from malware and redirects, all of [their] creatives are pre-scanned before they are served."
