I'm lucky that my group consists of people who are all my good friends and we've seldom wanted to 'evict' anyone. But I did assist in evicting one player from one campaign. We still play with him in other campaigns and he also GMs several campaigns for us.
We were preparing to start a new campaign with a different GM. The GM of the new game was a player in another campaign that included the player in question. Then the player in question took some in-game actions that left us all scratching our heads and muttering, "WTF?".
The GM of the new game decided at that point that he didn't want this player in his new campaign. We had intended to play the new game at the home of the player in question because he doesn't drive (and doesn't accept rides). So we just told the player that for reasons of scheduling and convenience we would be moving the game site to the GM's house. I think he might have been a little disappointed that he couldn't play, but otherwise the rest of our gaming interactions with him have proceeded as normal.
I have also been the player who was almost excluded myself. After we completed a long-term campaign and the GM started thinking about a new game, he emailed me that he wasn't happy with me and wasn't sure if he wanted to include me in his next game. I had done some things I knew annoyed him, such as reading or drawing during game sessions. I'd tried for a while to stop doing that but backslid. I also complained a lot about anything I didn't like in the game.
After the GM emailed me I admit I was upset. I hadn't realized just how much my behavior was annoying him. I think we could have done a better job of communicating with each other before it got to that point. But after I assured him that I would do my best to straighten up, he included me in his next campaign, which has been going on for 3 years now. I don't read during the game anymore, and I don't whine about stuff all the time, so hopefully I'm no longer doing anything to irritate him and he'll keep wanting to game with me.
