If I self host a Lemmy instance for just myself and maybe a few friends are there any risks?

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.

Could you share the cron/script you use to do this? I'm interested in hosting my own Lemmy at some point, and having a script for that cleanup would be hugely helpful for me.

Definitely! I'm hosting in Kubernetes so I won't post the full thing, but here's the actual command that I run hourly. Make sure to replace the values for database, username, and password.

PGPASSWORD=password psql --dbname=database --username=username --command="DELETE FROM activity WHERE published < NOW() - INTERVAL '3 days';"

Awesome, that was just as straightforward as I was hoping it was, thanks! I am more familiar with MySQL as I haven't used Postgres a ton but SQL is SQL after all lol

You're welcome! Makes sense. They're somehow so similar yet so different lol
