If a user’s name contains the exact phrase (case-sensitive), Hashbot will take action.

​
How It Works

When you add a phrase to your blocklist, Hashbot checks every new name for that exact case-sensitive substring.

​
Example:

/name-filters add phrase Pascal This will match:
  • Pascal
  • Sir Pascal
  • Pascalou
  • Pascal the Great
But it will not match:
  • pascal
  • Pasca
  • pascalou
  • pascal 123
Capitalization matters — phrase filters are case-sensitive.

​
Real-World Example

Impersonators often swap visually similar characters, such as replacing a lowercase “l” with an uppercase “I”.

​
Example:

If your team member’s name is Signal, a scammer might use:
  • SignaI (capital “I” instead of lowercase “l”)
To catch this, add: /name-filters add phrase SignaI Hashbot will flag any username containing this exact string — blocking the visual trick.

​
Best Practices

  • Use phrase filters for direct impersonation terms and known scam words
  • Target visual deceptions of team member names
  • Add both uppercase and lowercase variants if you want to catch all cases
  • Combine with Fuzzy Mode (Premium) for protection against Unicode-based spoofing
  • Use regex filters with (?i) for case-insensitive matching when needed
See how “SignaI” (with a capital I) looks like “Signal”? Phrase filters catch this kind of visual trickery. For broader case-insensitive matching, use a regex filter like (?i)signal instead.
