I've stumbled upon two different stories of former deviantArt members who's lives were ruined because of the crazed and demented members who obsessed over them, and made their lives a living hell.
It breaks my heart over the fact they had to completely abandon deviamtArt forever, because of what it put them through.
This got me thinking. Any one of us on this site or any other could become either the Victim or the Troll. So all I can say right now is... well... I think it's best to heed their warnings and be careful to whose profile you stumble upon, or which will stumble upon yours.
