Guild Wars 2

while i was rushing the enemy base in “battle of champion’s dusk”, one enemy player whispered me: “reported” , “now perma ban” and in the following seconds, my game crashed. What bothers me is that 2 members of my team got the same message from the same player and their game crashed as well. Is that even possible?

Theoretically possible. They might manipulate game packets to contain data in a bad format, directed towards your client, which then somehow passes the server but cannot be correctly interpreted (or misinterpreted) by your client -> crash you.

That makes me really worry.
