It's not that hard people 
Just kick everyone that isn't 4chan no if ands or buts about It.
If someone can't tell me their home boards or how they got here or basic board culture like filters then they don't belong and should be kicked on sight.
This "friend of a friend" shit is retarded and I've been saying it for years.

tldr gatekeeping exists for a reason and now we have unironic trannies in the meetups
