Scunthorpe Sans is a font based on Aileron that adds auto-censoring ligatures for a selection naughty words.
It’s able to detect the words f***, s***, p***, t***, w***, c*** and dozens more, but with a special exemption for “Scunthorpe”; that town has suffered enough.
It's available as a free download (Aileron is CC0 1.0/No Right Reserved).
