New update blocking invites to parties

If he keeps joining when it's an invite only party then someone is inviting him. Just block communications and ignore him.

For future reference, DO NOT accept party invites from unknown gamers, set 'Party Options' to 'Invite Only' and take control, accepting invites from these lowly individuals or communicating with them in any way opens a door for them to exploit, BLOCK COMMUNICATIONS
= Problem Solved...

That's clearly not the question I asked is it, if a person has been blocked they shouldnt be able to invite you to anything yet they still could so why is this able to happen? I received constant invites to games and parties of someone that wasnt on my
friends list and was blocked after the first few I didnt respond for over 10 minutes of the party invite message popping up on my screen

The Block feature I believe only stops game and party invites, chat requests and messages.

Hi everyone. I am not exactly sure what fixed this for me but it could have been that a 24 hour block reset something for me. It may help getting a 24 hour block yourselves to try and resolve this issue. 24 hour blocks are not bans like communications bans.
So even if you get this block, it won't go on your record and you won't lose any privileges for getting this block such as Xbox live ambassadorship as these blocks are not enforcement action and is done automatically by the Xbox live system. In order to get
this block, you must exceed your daily limit of messages. The best way to do this it to go to your friends list and send party invites in quick succession to all your friends, perhaps multiple invites to each one as messaging would take too long. Party invites
are considered as messages in the Xbox live system. It is best to tell all your friends first so that they know what you are doing. Make sure you don't do this to the public or recent players. Once you get the block, your messaging situation will be the same
as with people not on your friends list except this time you will not be able to send messages even you keep spamming the send message button/invite to party button. You will now not be able to send messages or party invites for a 24 hour period to anybody
including your friends. Game invites, Friend requests, Party chat invites, Video Kinect invites and in game communications will still work though. Once the block is over, there will be no remaining effects of it. No points added to your account or anything
put on your record or reputation, it is just temporary. Hope this helps!
