Global blacklists let you block a domain, app, placement or IP once and have it apply across every campaign on your platform.
One-click block works straight from any report — spot a bad placement in your data and block it without navigating anywhere.
Whitelists work the other way round: an account-level list of sites and apps attached to many campaigns at once. Change the list once and every campaign that uses it follows. See the Whitelists plugin, or buy ready-made checked lists through the Curated Marketplace.
Per-source quality controls let you tune filtering per traffic source, with a per-campaign "filters off" option when an advertiser wants maximum volume and accepts the trade-off.
How to run blacklists sensibly
- Block at the global level anything that's bad everywhere — known fraud domains, irrelevant app categories.
- Block at the campaign level anything that's merely a poor fit for that advertiser.
- Review the list periodically. Blacklists only ever grow, and a list built over two years can quietly strangle delivery.
Blacklists are not fraud protection. They're your manual layer on top of the automatic one — see How AI-powered fraud detection works, which blocks known threats before your budget is exposed at all.
