			=== Make all the accounts force follow one specific account ===
			Assuming you want everyone to follow <code>@lurk@post.lurk.org</code> then you would do the following:
			su mastodon
			cd ~/live
			RAILS_ENV=production bin/tootctl accounts follow lurk --verbose

			Notes:
			* It can be ran live while the instance is up and running
			* It takes a while for the command to get going, and it may spit a few warnings, then after that it's '''very''' quick and the <code>--verbose</code> flag helps to keep track of progress
			* At time of writing, there's no way to specify which account(s) will be affected, everyone will be processed

			Sometimes, specially when disk is full, postgresql may have crashed, and mastodon-streaming service will start but internally enter a loop of complaining that it cannot connect to the db (super annoying because to see that you need to examine the status of the service), anyway:

			service postgresql restart

	Deleting media attachments is not enough! Since Mastodon builds a local copy of every account it knows in the fediverse you will see the folders <code>/home/mastodon/live/public/system</code> balloon over time. Many instance admins [https://discourse.joinmastodon.org/t/clean-instance-unused-accounts-older-media/1182/6 are] [https://discourse.joinmastodon.org/t/ballooning-avatars-and-headers-folders/2049/4 dealing] [https://github.com/tootsuite/mastodon/issues/9567 with [https://mathstodon.xyz/@christianp/102655520448724916 this issue] and the prevailing attitude to solving it is to get more storage, which is bs.

			Once you have that list use a scripting language to parse it. The below example is in python. Its suuuuuper slow so probably not the best way to do it. Calling rails like this is not so smart I guess. But hey it works. It went from 11.5GB worth of headers and avatars to 7.5GB.
