Is it possible to automatically subscribe to all (federated) communities with the same name?

Example in the screenshot: I want to follow !astronomy, and I don’t really care whether the content is coming from from Lemmy.World, kbin.social and mander.xyz - I just want to see it all.

Obviously I could manually subscribe to them all, but is it possible to do so automatically? Ideally if a new similar community pops up on another instance, I wouldn’t miss it.

I read here that community grouping is a thing, so that instances with identical communities can work together. Is that a feature that could work towards this end?

    How are you hashing a password with a random 32 character string? I feel like you are mixing terms here or so you combine the password and the random element first or do you mean you decrypt the hash with a symmetric algo and get the 32 char string?

      Ah, sorry if I’m being unclear.

      I was thinking of combining the user’s original password with a random 32 Character string and hash that combination. So basically salting the User’s password with random strings. That should work out to multiple passwords I can use.

      Thinking of it bcrypt does exactly this, so just running bcrypt a couple of times should be sufficient, no?

      Security wise if there was a breach, an attacker would still only have a couple of hashes, none of which are the original password and they can’t dictionary attack due to bcrypt.

      Also, if an instance was hacked, the worst case would be that the attacker gains access to the hash (if the instance stored passwords in plain text and didn’t also hash them themselves).

      I’m really tired right now so maybe none if this makes any sense, but I think it does lol.
