bad-checker

A fuzzy, keyboard-typo- and leetspeak-aware content blocklist for Python.

Install name: bad-checker  |  Import name: bad

Usage

import bad

if "something bad" in bad:
    print("Caught it!")

Matching combines:

• direct substring lookups against a blocklist
• leetspeak normalization (v1agra -> viagra, fr33 -> free)
• a keyboard-proximity-aware Damerau-Levenshtein distance, so typos on physically nearby keys (and adjacent-letter transpositions) are caught cheaply while unrelated words are not

Add your own keywords at runtime:

bad.add_keywords("mycompanyscam", "internaltermtoflag")

Install

pip install bad-checker
