I opened the link, a description says "Hau weg die scheisse" which is German for something like "get rid of the shit". The money is transferred to 1brain7kAZxPagLt2HRLxqyc3VgGSa1GR The link points me to this thread http://www.reddit.com/r/Bitcoin/comments/1egi51/there_is_currently_over_10000_unconfirmed/

Pastebin does not use https. It is possible he did not hide his IP, so write the admins at pastebin. [email protected]
also write the guys at [email protected]
Once you get the IP, use whois to find the ISP. Contact them about the abuse
Please don't use the term "thief." The money was sent to a public address that anyone can access. That's not stealing; that's withdrawing. He didn't break into an account. He didn't hack anyone. He simply took money from a public account. Nothing wrong with that.
