Sometimes you just need to get away and start over.
I was so pissed when I decided to close my previous account, because I loved it, but I was losing interest in posting new stuff since some looser from my town started stalking me and trying any excuse to meet me (cross-stitch work for his daughter? you wish...).
So I deleted all my deviations, wrote goodbye on my journal, and here I am. New start!
I know, I know... I could have put him in the blocked users list... but it's not enough when it comes to that kind of people.
