A new user is registered under the name "coinflipz" who is sending out phishing PMs. They send what looks like a link to a bitcointalk thread, but the actual link is different from the text, linking instead to
http://bitcointlak.my-board.org (actual link is a bit longer leading to a clone of the Bitcointalk.org login page).
The PM I got was targeted to me as a pool owner. I'm not sure how many others are getting something similar.
