&gt; That being said, Facebook does let you chat via Jabber.<p>Facebook planned to shut down that service since 2015&#x2F;04&#x2F;30, and in my experience they actually did it around 2015&#x2F;07&#x2F;12<p>I&#x27;m puzzled as how you haven&#x27;t realized it... I guess that the xmpp endpoint might still be working for some users?<p><a href="https:&#x2F;&#x2F;developers.facebook.com&#x2F;docs&#x2F;chat" rel="nofollow">https:&#x2F;&#x2F;developers.facebook.com&#x2F;docs&#x2F;chat</a><p>Approaching that event, I warned friends to stop contacting me on Facebook, since I would stop checking its messages. (all of my email&#x2F;phone&#x2F;chat contacts are available in my about page, so it wouldn&#x27;t be difficult for people to adapt)<p>The problem is that there&#x27;s no way to disable the chat, so people wouldn&#x27;t mistakenly use it to contact me. And since I still use the facebook web page somewhat regularly, I wanted to avoid falling into the trap of using actively another walled chat protocol. My kludgy solution was to go and &quot;mute&quot; every single conversation I had in the last year. It basically never happens that new people write me on Facebook, and this way I can still check the messages once in a while, but de-facto I&#x27;m not actively using their chat service anymore, thus hopefully not contributing to the network effect.
