From what I could sadly see, the banning of a certain individual, isn't too much of a punishment. Since, and again, from what I could see, a lot of those "permanent" bans, don't do too much, as the said banned people find a way to by-pass the sanction. And while, some of them are just trolls, who could be silenced with an ignore, the case of stalkers or those who harass someone, it's worse on so many levels than just some trolling.
And from what could I saw, regarding a friend of mine. Someone began stalking her in here, till the point when he began stalking her in real life too. So yes, stalking and harassement shouldn't be addressed too lightly.
