Your account is not currently suspended.
We cannot lengthen the inactivity length, it is what it is for a very good reason. Once a month is plenty of time for people who want to keep their accounts to visit even if a lot of stuff is happening all at once, while being short enough so we can get rid of old accounts that don't get used anymore to free up disk space.
If you do not like the inactivity requirement, you can purchase prime membership, which removes that requirement along with giving you a slew of other features. See
http://x10hosting.com/prime-membership for more information on that
