Your home game has gotten out of hand. At this point you are running risks. You don't know all the players and you don't know who they are talking to.

Put aside the the legal risks. You are inviting trouble. You make your home game a target for robberies, problems with the neighbors (too much noise/traffic) when some guy you don't know at the game takes a swing at another player and a brawl breaks out you are the one who will have the damaged home.

Now if you are raking this game and making enough money to accept these risks, then that is a choice you make.

But if the only thing you get out of this is the chance to play in a live game, I think you should give some serious thought to scaling this game down to only people you know and trust. Don't allow other people to invite friends without your prior approval. And insist that someone else host the game from time to time.
