Still really haven't found a solution to the ballooning mastodon system/accounts folder. It keeps getting larger and larger. It's rather ridiculous that it must have 8.5GB of avatars and header images cached for a single-user instance. I simply don't see that many people on my timeline. It's almost as if mastodon is a slow-growing cancer growing on my server's hard drive waiting to consume the entire thing.
I picked a random avatar in the gargantuan pile of them on my server and did a query for it on the database and found out I haven't even seen the user in my feed since March of last year. Why is this still cached on my server?
I think I might see about querying the accounts table on the database for ones that haven't been seen by me in <insert time here> and then just removing them. If I ever encounter the user again it'd be gone. The cull command obviously doesn't catch them all because if it did I wouldn't have randomly picked that one I hadn't seen since last year.
