G'day Thanos,

"... insulting private message ..."

Here's some actions that would keep such messages "private". They are not presented in any particular order; nor is there any suggestion that they are mutually exclusive.

• Take no immediate action beyond deleting or archiving the message.
• Stop more messages with /ignore.
• Attempt to resolve the issue via private messaging.
• Choose to continue the fight and trade insults via private messaging.

As a last resort, read about "court of last appeal" in gods: this would now involve a few other people but otherwise still keeps it private.

What you definitely should not do is respond to a derogatory private message with a derogatory public message. The fact that you did this was my motivation for this response: I have no interest in people's private squabbles.

[I realise english isn't your first language, and maybe suggesting putting chlorine in one's mouth was an unfortunate translation of an idiom from your native tongue; however, chlorine is poisonous, it's been used as a chemical weapon in warfare, and putting it in your mouth can cause serious injury or death. I don't believe you were advocating self-harm or suicide.]

In closing, I'm definitely not taking sides in this, and have purposefully not voted on any of the nodes in this sub-thread.
