Looking to maybe self host my own instance, I’m still learning about the fediverse. If a different instance that I federate with hosts something illegal are there risks to me? Is anything from other instances hosted on my server like a copy of it? Or would I only end up hosting things my users post? I’m paranoid and sorry if this is a silly question.

      I’m running it in the smallest VPS of vultr with 25GB of disk.
      This instance only has 3 users, with me being the only active. It says it’s been up for almost a month and I’ve only used 3GB.

      Here are the docker volumes which have the actual data of your instance, and from inside the DB the biggest table is the one called activity which the devs said it’s only sometimes used to validate the data, but could be truncated if needed (there’s a schedule task which only keeps up to 6 months).
      Also the thing to have in mind is to properly configure the logs of whichever installation guide you follow.
      After that I’ve seen other admins say the next biggest is the media uploaded (from bigger instances).

      $ du -h --max-depth=1

      lemmy=# select
        table_name,
        pg_size_pretty(pg_relation_size(quote_ident(table_name))),
        pg_relation_size(quote_ident(table_name))
      from information_schema.tables
      where table_schema = 'public'
      order by 3 desc;
               table_name         | pg_size_pretty | pg_relation_size
