A small script to list which of the people you follow are visible in public twitter autocomplete searches.

banned-friends.rb

#!/usr/bin/ruby

# This script tells you which of your friends (people you follow) are
# auto-completable in public twitter user searches, e.g. by typing
# @username" into the search box. It takes four arguments for twitter
# API credentials: consumer_key, consumer_secret, access_token, and
# access_token_secret. You can create an twitter API app at
# https://developer.twitter.com/.

# Output is a tab-separated list of accounts, one per line, where the
# fields are: visible-in-search, screen name, display name, description.
# 
# For instance:
#
# false	mancsbondage	That guy in Manchester who does stuff with rope...
# true	anarcho_slut	🌹june amelia rose🌹	anarchist leatherdyke fiction
