    Hey Kimberly, 

    Make sure you are following the correct format when adding in your blocklist. For reference:

    • When using keywords, type the keyword followed by a colon with no space after the colon (for example, Separate multiple entries with a space, and add the keyword before each entry (for example, See Allowlist and blocklist usage examples.
