I signed into deviant art and everything was gone what happened to my deviantations?

-i went to the website: deviantart.com, to look at the new drawings my friend had made. but i had to sign in first... when i did i noticed that i had no favorites but i know i had many, that's when i also saw that i did not have friends or the poems i had done, i know i probably cant get it all back but i just wanted to know why this had happened. also i was not hacked or anything because the pass i used was very random as f***Just because you have a super random password doesn't mean you didn't get hacked. You need to get a hold of deviant art because quite frequently website servers as big as that usually do a weekly back up of their database...
