So I’ve been wondering lately if its bad practice to ban a user if they send the server a bad packet structure. What I mean is this, if the server is looking for a 24 byte packet but the client only sends 10 would it be a good idea to ban the client for packet manipulation. I realize that with the UDP Packet structure this would be a bad practice, however for TCP would this be a way to negate exploitation because if someone even attempts to manipulate a packet, they would be banned instantly by the server.
What are your thoughts on this?
