It's entirely up to you what you do. It was deleted as SPEEDY A6 attack page, namely: 
 #Attack pages. Articles that serve no purpose but to disparage their subject or some other entity (e.g., "John Citizen is a moron").  This includes a biography of a living person that is negative in tone and unsourced, where there is no NPOV version in the history to revert to. 
 You can accept that, or, if not, your option is at Undeletion policy], namely to request a Deletion review. This should not be taken as any comment by me on the deletion itself, but is just to acquaint you with procedures.
