I noticed that there were some accounts that were hijacked by the instance owners. All the posts from that user were then edited to say what happened.

This kind of surprised me, I figured instances could delete posts, but not edit them. So how much control do they have?

I assume they can't see my password (hopefully). Can they post in my name? Do they have all the access to my posts to foreign instances that they do over local posts?

Edit: thanks for all the responses everyone! I've wanted my own instance for a while, but maybe I'll get on it now

  • Password hashing occurs server-side. Even without removing the hashing step an admin can intercept the plaintext password during login. Use unique safe passwords.

  • An admin can intercept the jwt authentication cookie and use any account that lives in the instance.

  • Private messages are stored as plaintext in the database

  • Admins can see who upvotes/downvotes what

  • These are not things that are unique to Lemmy. This is common.

  • To avoid having to trust your admin, run an instance.

Can you recommend a good free web host for running your own instance? I haven't dabbled in web development in over 15 years now, so I'm kinda out of the loop.

Oracle has a pretty decent free tier.
