This is a opinionated blacklist 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 blacklist 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

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

This repro contains standard data files, just pick the format of your choosing.

• newline: list.txt
• json: list.json
• python: list.py
• javascript (es6): list.js
• javascript (commonjs): list-commonjs.js
• php: list.php

The blacklist has both a python and node library available.
