That's odd. I can assure you that there is no banning going on of any kind, though. Something might be going awry, but the word "banning" can be a sensitive word. Make sure that they are getting the new invite link from the new game. If that is not working, try sending them a link from a brand new game, just to verify that there is no overall problem. If you want to verify that kicking someone from a game does not disallow them from using a newly generated link, you can create a Dummy Account , invite it (and log in under it), kick it, and then invite it with the new link. It should work fine. If all this still goes awry, please fill out a Help Center Request , because something is not working properly. Also, please, if you could, report back to this thread regardless. If there is still a problem, I'll do what I can to direct attention to it. If you manage to resolve it, it would be helpful for others to understand what the issue was.
