I've done this some time ago. I'm trying to think of places he/she may have gotten it from. Clearly it wasn't here for SF. The only other place I could think of was EVE Online or Game of War: Fire Age. Most of my EVE Friends have it because we would do fleet OPs at random hours of the day. I'd get a mass text from the server when an OP would start.
I think Corrine may be right, but I'm going to figure out who this person is. I won't break any laws, and if things end up going south, then I'll just block the number.
