I just got email from keyword tracker with my username and password and it seems someone is playing with password retrieval ! I don't know why but it seems they just enter your DP username
Check out the last post in this thread to know who it was iabtm. http://forums.digitalpoint.com/showthread.php?t=208080&page=3
Ah I see big thread about this .... well ... as long as they don't get password it is good ... email .. nothing to worry about I guess
