my adsense account has been approved 2009 . and i am using it since then. i was a novice then and did some celebrity gossip and news stuff. later i earn pretty good from adsense. avarage earning from it was 1000 dllr. my highest earning was 4200 dllr. all on a sudden my account was vacant with 83 dllr in my account. while i log in to my account it shows the first approval windows which i saw back in 2009 before my approval with a celebrity gossip site. why this is happened to my account? is it a ban or what else..?
