Just denied for a musicians friend credit card (HSBC)

First off i had the CC before and they deactivated my account after 2 years of no use and told me I had to reapply. So i do it and i get denied, so first thing im thinking is I hope no one stole my identity and wrecked my credit. I go and check my credit score. 777. What sort of fricked up process are they using to approve credit cards now a days.
