Chinese hackers use it a lot. That is one of the first things that I uninstall. If you see it I guess the rice-eaters have it in for you. I got hacked literally hundreds of times through Telnet.

You probably mean the telnet client, don't you ? That would be a much smaller opsec risk, if at all. It is the telnet daemon that is the problem here.
