Ping kicker decreases with popularity.
The lesser populated server (like 20/64) have much higher ping-limits than when you join 64/64.
VIP-Slot prevents you from ping-kick, though.
Hi B4n4n45p1i7, thank you so much for the fast reply,
See, but that's kinda strange, because yesterday I'm joining #PB1 & #PB4 with 40-50 players but didn't get kicked.
I might wanna give it a shot again, but I'm too afraid because in the server description, 3 times i get kicked, I'll be banned (?) Haha
