Every method of communication known to man short of identity verified channels is a potential direct route of communication from a child to a pedophile. No, I don’t think that Lemmy, Discord, Reddit, Xbox Live, PSN, Steam, Twitter, Tumblr, XMPP, Signal, 4chan, Whatsapp, Snapchat, Messenger, SMS, or IRC should be shut down because of that potential abuse case, and I don’t think that Nintendo should avoid a decent friending/communication infrastructure because of it. And I’ve been using some of those services since i was a child.
