Before a coin gets in, the bouncer checks it on-chain. Who holds it comes from pump.fun's own holder data, and the climb comes from its bonding curve on Solana. It needs four of five, and the climb is mandatory.
Every coin launched on pump.fun shows up at the door the moment it's created. Most of them never make it past the rope.
When the club is full, the door closes. A coin only gets in when a slot opens and it passes the check.
If a coin inside starts dumping, or its holders turn bad, the bouncer throws it out and the next one in line gets a shot.
Launch on pump.fun from your own wallet and your coin goes to the front of the line. It still has to pass the check to get in. The bouncer doesn't take bribes.
