ONLY advertise your service in SoD’s Trade channel. If you advertise in any other channel (General, Local Defense, LFG) or /say, /yell, etc., you will be reported and you will be sanctioned.
There was another person recently who found themself suspended because they were trying to sell rare kills, but they were hitting multiple channels (all the wrong ones), and that’s what got them. Not the service they were offering, but how they advertised it. It’s a fairly short thread, but lots of information in it.
