The game is F2P, it takes less than 2 minutes to create a new account.

 

Note that the IP address cannot be spoofed because before sending the connect 
packet you must get a challenge value from server…

Subject: Re: [hlds] Client 0 overflowed reliable buffer

 

Don't even think the name has to have garbage characters, it would probably 
work equally well if the player was just connecting with a long name. Events 
are reliable, such as player_connect and player_disconnect. So repeatedly 
connecting and disconnecting within a second will result in a huge amount of 
events being distributed to all clients, and hence overflowing the reliable 
buffer. I can't imagine this being fixed shortly, without banning Steam IDs 
(you need a Steam auth ticket to connect to servers).


 

 

Kind regards,

Saul Rennison

The issue is legitimate, it's caused by having a client with garbage characters 
in their name connect and disconnect repeatedly.
