I’m sorry, but it’s probably in your best interest to do some research and actually read the discord Terms of Service and Privacy Policy before arguing about something you lack knowledge in. Creators of a Discord server are not responsible for members’ data that they send to Discord. That relationship is between Discord and the Member, not the creator of a server. Any “contractual agreement” you are talking about is covered when you click “I agree” when creating an account, the devs’ accounts included.
This is a ridiculous argument that has a correct answer that Discord themselves will tell you.

I’ll be honest, I don’t even know what you’re asking. Discord owns all data on Discord. Server “owners” do not own anything from a data security standpoint. If you are asking a question in good faith, please rephrase it into smaller sentences. If you are arguing in bad faith, I have no desire to continue this thread.
