A section in AVID is the IP/Domain Black List Section. The icon is a circle with a slash through it located in the main menu bar on the left of your AVID home screen (as seen below).
This feature allows you to completely block known bot traffic or other bad traffic by a single IP address, a range of IP addresses, an IP block of addresses, or by domain name. You can add as many IP addresses or domain names as you like. Anything blocked by the black list will not show up as impression data in your regular stats.
