If you didnt actually delete your account (which you can do, otherwise under normal circumstances its just suspended) you can do that.
The first time I suspended it, the second I deleted it but what I understood was if I wanted to go back.. I could. There was nothing to warn me that I could never gain access to it again-- at least not at the time. Yes we are out there however all that was willingly put out there was a few comments and a lot of photographs. From that should not come my personal registration info like name, addy, panty size.. you know.
