It seems there may be an undercurrent of malicious PM’s floating back and forth between some members in relation to issues with other members.
Whilst admins/mods won’t pry into personal messages, it is quite within the rights of any member to forward a PM they have received on to management for action.
So, to those sending or contemplating sending such messages, be warned that anything you write in private could well be used to take action against you if the receiving member decides to forward the messages on.
The code of conduct applies in PMs to the degree that the two members are not consenting adults. Please keep that in mind.
