With defederation left and right (basically isolation but a bit more complex) the 1 account rule isn’t necessarily true but starting out it’s enough if you have one acc and then when you hit a block (you want to find a community/instance which you know exists but doesn’t show up from your instance) then you can start thinking about making alt accounts on said instances.
Currently I have 3 accs because the instances defederated each other and there is no other way for me to view some communities like this. But the android app (jerboa as well but I recommend Liftoff) makes switching between accs easy.
