# Script to find your fedi mutuals' websites.
# In the spirit of nerd fedi's desire to bring back self-owned websites, blogs and RSS feeds, this scripts finds all
# your fedi mutuals, and grabs the URLs from their custom fields. By default it only returns "verified" ones on the
# assumption that these are probably personal sites not other randomly-linked things, but you can turn that off if you
# like. Definitely works on Mastodon, not tested on anything else, sorry.
