I just boosted our @mastohost plan for #SubduedSocial from the $19/month to the $39/month plan. (#SubduedSocial users can read more about it in the server announcement).
Seems like we're running into the issue with an ever-growing cache content database and the lack of the ability to delete old content but still preserve any old posts that our users have favorited or interacted with.
Thanks @hugo for drawing attention to this missing feature in Mastodon: https://github.com/mastodon/mastodon/discussions/19260
