Clbuttic
Updated: 04/26/2017 by Computer Hope
More commonly known as the Scunthorpe problem, clbuttic is an issue that occurs with filters, such as spam filters, that mistakenly block or deny something that is valid. The Scunthorpe problem derives from the 1996 AOL (America Online) swearword filter that blocked users living in Scunthorpe from creating accounts because of the obscene keyword in that town's name. Clbuttic is an issue that occurs with a search and replace technique that replaces swearwords with valid words. For example, replacing "ass" with "butt" in the word "classic" would make it "clbuttic".
Today, both terms describe any similar problem that is encountered with software filters or search and replace regular expressions.
