Blacklist domains using an external text file and check if what you see has been blacklisted or no.
BlackMarker is a Chrome Extension which helps you to avoid potentially toxic or penalised domains. It's powered by a database of "bad" domains, which is updated regularly. The toolbar icon will turn red whenever a website you are looking at is on the BlackMarker list.
