Is Lemmy Connect the first and currently only way for individual users to block instances? I know you can block instances if you host an instance yourself, but not everyone wants to do so.
We should be promoting this feature if indeed we are the only one with it as it has been in popular demand, especially lately, with Threads now being a thing.
Ideal implementation (IMO) would be a thin note in the comment string indicating a comment from a blocked instance user, to fill in context for you that there is a reply there that others can see, but is not being shown to you by default.
You can then read it (if you wish) by expanding it.
