You're always responsible for what you, yourself and your computer does. There is a chance EFF/some other organization could help you out in case you end up in court, but that's a maybe, not a guarantee.
Harder to make this argument with encrypted distributed filesystems. If I'm storing a single chunk of an encrypted blob on Filecoin, am I responsible for the entire file even if I don't know what's in it, and I'm only storing a single fragment?
This depends on the jurisdiction you're in. I.e. Europe's GDPR argues that you need consent to keep someone's personal data. Encryption doesn't equate anonymization, so there's a potential liabity.
