If you block a contact, presumably that means you don't want them to see your presence and you're not interested in theirs. In that case, presence going stale is unimportant (shouldn't be shown anyway?), and any kind of probes would be considered a leak.
There may be a small case for still viewing their presence for spying purposes, but I'm not sure it's worth the extra complication. [Possibly worth contrasting with XEP-0186 (Invisible Command) where you would still want to view presence.] ________________________________ From: Standards <standards-boun...@xmpp.org> on behalf of Kim Alvefur <z...@zash.se> Sent: 20 June 2019 20:31 To: standards@xmpp.org Subject: [Standards] XEP-0191 leads to stale presence? Hi, While working on a fix for Prosodys XEP-0191 implementation¹ regarding presence sent to a blocked JID to pretend that the blocking user is offline, and then re-send presence again if they unblock. However, since if you block someone, your view of their presence will become stale. The XEP does not say anything about this. Is it implied that the server should send a presence probe or otherwise try to do something about that? ¹ https://issues.prosody.im/1380 -- Regards, Kim "Zash" Alvefur
