For reference...

Why Accounts Become Disabled:

When your iTunes Account has been disabled, and that often happens due to suspicious activity --- Perhaps nothing on your part. They disable it for no more than Security & Privacy concerns.

Possible Reasons Could Include: 

• Too many unsuccessful login attempts
• VPN (Virtual Private Network) usage
• Consistent transactions
• Session Times Out
• Disobeying Terms & Conditions
