There’s been a few posts here in the past on this (like this one), but since the system locks them after inactivity I can’t revive discussion on the topic, but the gist of this issue is that
system/accounts/headers are gigantic in size on my server which is just a single user instance because Mastodon doesn’t remove old avatars and headers when removing old media with the tootctl command. This is a problem because the folder will forever get bigger and bigger without a way to remove old images.
There is an open issue for this, but what I’m asking here is if there’s a way for me to get rid of old ones manually without breaking Mastodon? Because if I just delete images from the folders I’d end up with a bunch of broken images in Mastodon. Eventually pretty soon these folders are going to get too big.
