I'll add my 2 cents to the pot (I'm french, and spend a lot of my time in the FR section).

I took the weekend off and didn't see the death threats and the heated arguments that just happened. So I won't comment on those.

The user Danydee is somewhat sometimes "annoying".
In my case, I don't know if he wants to be my friend or just curious or just a stalker.
He messaged me a few times, trying to guess my name, my job, and my exact location, sometimes just sending a simple "hello" or a "how are you"...
It could have been because of curiosity, to befriend me, to troll  or for some other less acceptable actions.
On the other hand, he also sent me a few messages about sig campaign, free raffle (before the "no PM rule"), so not all bad.
I ignored all the messages, he calmed down and stopped messaging me.

Is a temp ban justified ? I will let the "law-makers" decide.
Are 7 days to much? to little? I don't know. Let the law-maker decide.
But he does change his/her/its behaviour, the next time might be a permaban.
