Feel bored today then i decided to check my old email and found that i registered with this name 3 years ago.

No don't worry - I'm sure there are plenty of usernames with the letters "NSA" all over the internet. Could be an acronym for a lot of things just see https://en.wikipedia.org/wiki/NSA_(disambiguation) for examples
