I noticed that some instances put a registration wall behind their communities. If you are registered in instance A, you can search for a specific community in instance B but cannot see the full list of communities there. Is there a workaround (besides asking someone from B to give a list of the instance)?
There is https://browse.feddit.de/, but it doesn’t have everything (missing lemmy.ml for one). And showing every community on one instance would require unselecting every since other instance.
