I wonder if a solution is not to try to contain the 'pressure', but to give it a release valve. Instead of trying to detect and push them out, give them a chance to say their piece and make their connections. If they have a reason to out themselves, then they can be contained.
HN does this too - you'll see the ads occasionally for startups, and we're all glad for the 'who is hiring' and 'who wants to be hired' threads. Those are likely containment as much as anything else.
