I agree, this is a problem we haven’t addressed yet. We’re working on it, soon Seedit will have its own communities specific to a reddit-like user experience. All the 4chan-like communities will be transferred to the Plebchan client. I’m talking about “default communities”, i.e. those recommended by the app when first opening it (when the user isn’t subscribed to any subplebbit address yet), but of course nobody can stop users from connecting p2p to any community, no matter from which client.
