### backup regex generated from it.  Both must updated and kept in sync.

# Please only add entries that you manually verified as actual working
# redirectors that can have abusable custom URLs.  Adding non-abusable
# services only generates unnecessary HTTP requests.
#
# After any changes, also update __URL_SHORTENER regex at end of file.
