I just verified it is indeed a valid suspension because you are violating the rules regarding how often you can run your cron jobs.
"* Crons: We do not allow more than one cron within a 5 minute time period per account. This means if you have two crons you must make sure that both do not go off within 5 minutes of each other."
You're running 3 every minute. That's the reason it suspended you, as the scripts themselves are actually taking a fair amount of time to complete running, so it's picking you up for excessive commands.
Until you agree to remedy the issue, I've applied a semi-permanent suspension, as it is indeed currently breaking the terms. You're more than welcome to agree to fix them, but in order to be in line with the TOS, they not only have to run every 5 minutes instead of every 1, but you can't have 2 execute within 5 minutes of each other, so if they are all set to run every 5 minutes, it'll -still- break the terms. You'll have to do something similar to running one at 0, 15, 30, and 45 minutes after the hour, the next at 5, 20, 35, and 50, the next at 10, 25, 40, and 55.
In short? It's valid, it's in the terms, and while it's not permanent, it was indeed suspending you for a legitimate reason. You're welcome to fix it, but as it currently stands the system was indeed suspending you for a valid reason.
