Dear Okurkabinladin,

Your Bitcoin Forum (bitcointalk.org) email address was just changed from polacek.michael@gmail.com to polacek.michael@gmail.c3om by IP address 188.165.146.195. If you did not do this, then you can visit the following link within 14 days in order to lock the account:

Note that you will NOT be asked for your password at that URL.

Of course, I locked it down afterwards. Any suggestions on the meaning of this? Or motivations behind such ruse ?

I havent logged into that account for weeks.

P.S.: That IP address is from the United Kingdom. I am based in central Europe.
