Well, I am hosting this instance on a VPS, also given that I currently reside in a third world country, my pay is shit that I cannot afford more storage. If there comes a time that I would have to delete some posts and comments to free space, given that I still have not explored the Postgres database container, I hope the devs included some foreign keys on the comments table that would make deleting stuff way easier.
As a cheapskate selfhoster who can only afford a few gigabytes of storage, It may come to a point where 30GB would not be enough to host the entire post history of the lemmy fediverse once user activity rises, and only those with deep pockets would be able to host archives of lemmy posts, just like usenet servers.
The only way that you would get caught is when the government is involved, unless somehow you have acquired the server or the domain using crypto.
Might wanna be careful with rice, that shit makes it easier to get fat, lots of carbs in rice.
