[tor-relays] New month, new TOR exit servers, need ELI5 pls

[Markus Koch]

As I told you guys ITLDC.com kicked 3 of my exit servers last month.
Just got 3 new ones, hosted by DigitalOcean, Hostwinds and soon
virtualniserverlite.

If things go wrong (and with my luck they will) how many and which
ports do I have to forward to be useful as a exit node?

eg: I get lots of abuse of port 22, can I close it and the TOR network
will for itself find out that sending me ssh traffic is a bad idea?
