As of recently, there are still players and server admins kicking users for high pings. This is no-go as players with high-pings do not affect the server or its connected players.
The following was a statement made by the Associate Producer Mike "Acekilla" Aubuchon during an IRC Interview which confirms this.

I want to set the record straight about players with high pings causing lag - this is a MYTH. It is impossible for a player regardless of how high their ping is to cause server lag for everyone else.
I will spare you the technical details, but it has to do with the UDP protocol used for network transmissions in the game, and the Unreal Engine netcode specifications. Please do not votekick anyone with a high ping off a server because someone thinks he/she is the cause of the server lagging.
You should not vote-kick or admin kick any players who have a high ping. They do not affect you or any other player on the server.
For more information on this, please read the specifications of the UDP protocol.
