I don't understand the allergy mechanism, though. Can't you just... mute the bad actors? I can't grasp the frame of mind where I'd need to preemptively mute people who are (believed by some guy known only as "Tom" to be) shallow VCs.
I mean the boring answer is that people have patience and energy constraints. They arbitrarily ignore the whole group because VC isn't adjacent enough to their life goals, or something, to warrant the energy necessary to pick out the patience-stealers from the insight-givers.
