If I recall that port correct, it's used for IRC. So your exit relay would benefit people using IRC. If I recall correctly, you need ports 80 and 443 to get the exit flag so it might not work for IRC at all. That said, you still benefit the network as a middle relay helping with hidden service traffic, potentionally being a user's guard, among other things :)

If just 1 port would be opened at an relay, eg. 6697, would this help the Tor network or would only spammers and DDoS use that port?
