This is a opinionated blocklist of words that you might not like to see used as usernames in your service (think username.domain.com, domain.com/username or username@domain.com).

The editable blocklist can be found in list_raw.txt and is categorized into six sections:

• Privileges User privilege terms to prevent faked authority. Example: root, super
• Code: Programming terms that you might want to avoid in a url. Example: void, null
• Terms: Various technical terms. Example: request, system
• Financial: This is for the spammers/scammers. Example: payment, invoice
• Sections: Common website pages and sections. Example: faq, help
• Actions: User actions. Example: delete, create

You can try the blocklist using the tool Username checker.

Please note that this list does not contain any curse words, there are other lists for that.
