Yesterday night, I had just finished playing Minecraft PE with a friend and just as I was about to hop off, someone from my game invited me to the party (I had been playing on a PvP server). I was a bit confused at first but when I realized who they were, I left the party and blocked them. However even when blocked, notifications to join their party kept popping up through my Xbox Game Bar. What's the point of a blocking system if they can still reach out to you afterwards?
TL;DR You can still invite people to a party even when they have you blocked
