# FilterName

<mark style="color:green;">List of forbidden words/phrases when renaming a character (via the name change command) — if the new name entered contains any of these, the name change is rejected.</mark>

```
//Command Rename - Block name or part of the name
//Max 10 characters
//Label
"gm"
"Gm"
"GM"
"adm"
"Adm"
end
```

### <mark style="color:yellow;">Notes</mark>

* Unlike `Filter.txt` (chat), the comparison here is case-sensitive — this is why the default file lists the same word in multiple casing combinations (`gm`, `Gm`, `gM`, `GM`...) to cover all variations.
* There is no masking: if the new name contains any listed term (at any position within the name), the name change is blocked entirely, not just the prohibited part.
* The new name is also limited to a maximum of 10 characters — this is enforced before checking this file.
