Is it normal for an item to get blocked w/ no notification at all?

I thought Amazon normally notified you that there's a problem with your listing and you may not sell that item, but I have an item that was just blocked with no notification at all.

I know why it happened, since a competitor did a test buy.

It's not a big deal, I'm just hoping that it doesn't negatively impact my account. I'll just get that competitor suspended (I can play MUCH dirtier than they can) and then sell that product with a different account once there's nobody left to complain about it...
