I got notifications for both of them.</p>\n<p>I didn&#x27;t actually know that it was a standard part of the ActivityPub protocol for an actor to send a block event to the actor being blocked. It doesn&#x27;t seem like someone should know that I&#x27;ve blocked them, but I guess that&#x27;s the way it goes.</p>\n<p>Just FYI, in case you didn&#x27;t know (I certainly didn&#x27;t), someone might know if you&#x27;ve blocked or unfollowed them.</p>\n<p><a href=\"https://microwords.goodevilgenius.org/t/activitypub\" class=\"mention hashtag\" rel=\"tag\">#<span>ActivityPub</span></a> <a href=\"https://microwords.goodevilgenius.org/t/block\" class=\"mention hashtag\" rel=\"tag\">#<span>Block</span></a> <a href=\"https://microwords.goodevilgenius.org/t/mastodon\" class=\"mention hashtag\" rel=\"tag\">#<span>Mastodon</span></a> <a href=\"https://microwords.goodevilgenius.org/t/microblogpub\" class=\"mention hashtag\" rel=\"tag\">#<span>microblogpub</span></a></p>\n", "to": [ "https://www.w3.org/ns/activitystreams#Public" ], "cc": [ "https://microwords.goodevilgenius.org/followers" ], "published": "2023-01-14T21:59:52Z", "context": "https://microwords.goodevilgenius.org/contexts/dac7ab178057433aa04faea4eb3be9c3", "conversation": "https://microwords.goodevilgenius.org/contexts/dac7ab178057433aa04faea4eb3be9c3", "url": "https://microwords.goodevilgenius.org/o/4fd431364f2347cb9f04750a14ae2a44", "tag": [ { "href": "https://microwords.goodevilgenius.org/t/activitypub", "name": "#activitypub", "type": "Hashtag" }, { "href": "https://microwords.goodevilgenius.org/t/block", "name": "#block", "type": "Hashtag" }, { "href": "https://microwords.goodevilgenius.org/t/mastodon", "name": "#mastodon", "type": "Hashtag" }, { "href": "https://microwords.goodevilgenius.org/t/microblogpub", "name": "#microblogpub", "type": "Hashtag" } ], "summary": null, "inReplyTo": null, "sensitive": false, "attachment": [] }
