"face-to-face confrontation" are deemed hostile even as to me. what unjustified suspension?

you can worded it better but you choose not to. Maybe your intention is not wrong, but since you are choosing the wrong way to appeal, it just makes you look bad, and also made the admin decision to suspend you justified.

nope. I had read over the thread in where you confront to do so, nope, it doesn't seems to sound as you say. It sounds more hostile to me.

If you were to really meant it, then you can put it in a nicer way, such as "give me your phone number, maybe we can met up and discuss, and share our knowledge among us" or something like that, but you choose not to.

The same that you does not choose to email the helpdesk, but instead broke the law of the forum and create a dupe.

besides, i think you should already know, words are unable to show the feelings of the person who type it well.

the person who wrote it might mean 1 thing, but due to the words use, the person who read it might feel another way.

hence, choose your word rightly and don't blame others if they misinterpret.
