The question is are we committing an offence communicating with a known pirate? Which someone is if they operate on a frequency they are not licenced to use. OK in telling to Op he isn't supposed to operate on the frequency, but more than that? ....
The problem here is that you will never actually know what sort of license the other operator has (if any).
http://hflink.com/60meters/ says that Finland has more range than 5351,5- 5366,5KHz. True, but only with special permission, most hams don´t have it here.Same thing in other countries as well.
Why would one try to control something he can´t. It is the operator who is responsible what frequencies they use, what power they run etc. We are hams, not cops
