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.

Sounds like you just happened to luck out with this troll, and though your experience with him was relatively benign he obviously likes to poke members with sticks, so to speak.  That's what trolls do, and he seems like a fairly aggressive one at that.  I'm not one of those lawmakers, but I think the dude should be permabanned.  The crap he's pulled justifies it, plus I doubt he's the type of member who would learn anything after just being banned for just a short period of time.

Mais tu sais que j'ai les moyens de te faire pleurer tout ce que tu as pour me supplier de te laisser partir !
