Hi all, I have a difficult question to ask.
I'll be starting up an RPG group soon and already have a few players in mind to start up with, and I'm open to new players joining up in the future to expand my group. However, there are a few players in the community that I've played with in the past whom I do not want to GM for, for a few reasons. One in particular I'm thinking of is a player who decided to be edgy in a fun campaign and did something I would never be comfortable with in a campaign I'm running (urinating on an NPC captive specifically). Said player has just asked to join my campaign unsolicited, which brought up this problem.
How can you as a GM turn down players that you don't want to GM for, even if you're open to including new players in the future?
I feel that I can't have this double standard of being open to players joining but denying specific people from entering the campaign. It feels rude to turn down players that I don't like personally, and I'm forced to include them for the sake of politeness even if it will make the game less fun for me to run. The same goes for other players I don't want to include in the group for other reasons, such as playing slowly or not RP'ing well.
I haven't taken any action in this instance but if it comes to it I feel like I should tell the player first that I'm okay with the current starting number (four players, a fifth perhaps joining in a couple of weeks), but if I lose one or he persists, I feel like I want to tell him his behavior in the other campaign is not something I want to bring into this one.
I could say the campaign is invite only but that shuts down anyone else casually joining up that I may be ok GM'ing for.
I feel kind of stuck in situations like this. Any other GMs have some advice on dealing with players you don't want in your campaign?
