As you deduced, you were suspended for running 6 cron jobs in a day when the limit is 2 per day. If you need/want more cron jobs feel free to use a service such as setcronjob.com. I have unsuspended your account, if you still see the account suspended page please try clearing your cahe.
That account is not suspended and was last accessed on the 22nd. You may have brute-force protection so please stop trying to login for a while, if after that you still fail to login try to reset your password, and if that fails let us know.
