Yah but how up to date a relays information is depends. So can lose data still if a major relay hosting most of your content goes down. Also say if you leave a relay that has data and choose not to use it anymore/get banned you wont risk losing what was on that relay. Correct me if I am wrong but I know relays can remove, filter, or totally censor certain things.
