Currently: Not for a user.
The only way to block at instance level is defederation which is usually a bit extreme.

This shouldn’t be too complicated to handle at the user level, but someone would have to spend time to develop it and contribute to lemmy source code.

Likewise, there are specific instances for which I’d want to auto-sub to all current and future communities, which is also not a fair that exists (other than creating your account there and browsing “Local”)

IMHO, Blocking at the user level is a feature that’s relatively likely to happen eventually.

You’re saying I’m she 30 and olup?

Idk non English speaker misunderstood “giving the finger”?

I do client ssl verification.
Nobody but me or my household is supposed to access those anyway.
Any failure is a ban (I don’t remember how long for).
I also ban every IP not from my country, adjusting that sometimes if I travel internationally.
It’s much easier when you host stuff only for your devices (my case) and not for the larger public (like this lemmy instance).

After the self induced constipation, they’ll need the poop knife for sure.
