Citizens Against Ugly
Street Spam —
www.causs.org — is a non-profit organization dedicated to "the fight against the proliferation of unsightly, illegal advertising signs . . . for the sole purpose of stealing free advertising at the expense of the aesthetics of the community."
—Kim Canon, "Deleting signs an addiction for bandit,"
The Houston Chronicle, March 21, 2001
Street spam is also called
vertical litter and putting up such signs is called
flyposting.
Street spam is an example of a more general scourge called
bandit signs.
