Client's can run string commands on the server with no rate limit. This means when you run 50k+ commands that are unknown, or spam 30k 'status' commands, you will be able to hang the server for 800/1200ms (15k/30kms if script printing to console is enabled!). Although the netchan processing budget system will kick you, the damage has already been done at this point. This change effectively breaks the ability to DOS the server from the client using networked string commands. In easier words; binding 'status' to your mousewheel will get you kicked from the server, without hitching the server.
