Blacklist is a term that is used in paid advertising which refers to a specific filtering type that is meant to prevent certain websites from displaying your ads. This may be because the ROI from the website displaying your advertisements is really low, or it only doesn’t have any ROI whatsoever. If the quality of the traffic happens to below, that may also be a reason for blacklisting the website from advertising.
Any Publisher or source who’s behavior matches known fraud patterns is reported as mobile fraud, and blocked when possible.
Many anti-fraud solutions buy or maintain their own blacklists of Device IDs, bot signatures, and IP addresses known to perpetrate fraud.
Once an IP/Device/link is added to a blacklist, all clicks and installs from a blacklisted source gets blocked automatically.
