We don't tolerate bad ads, including malicious redirects. If you run into them, please report them according to these instructions.

Some recent sophisticated attacks have made it through even the most stringent provider filters because of the way they hide their triggers. We've gotten better at detecting these bad actors, but user reports remain the best source of intel in this arena.
