It depends on the campaign, really. I run about three in parallel. One of those is a casual game, run in a particular house, with a core of players that usually are there, and more who drift in and out. There are four who've always been there, pretty much, and as many as ten others in and out over time. I don't mind who plays in that one; most of them have become friends, some remain just acquaintances. We've a new player starting in that game this week.
A second campaign is run for a specific group of people - there are no more people coming in or out of it. They're all friends.
And the third, the serious one I invest most time in, is definitely and specifically friends-only. I screen heavily for it, and in six years, we've only had five players, four of whom are still playing - the other one moved to another country, which makes it awkward. I have no problems with telling other people, no, your style wouldn't match. Most people accept that, and play in the first campaign if they want to.
