Well, the 30 day suspension will end 30 days from the time it begins, but your account is as good as gone if you've been hit with a temporary suspension. That counts as a MAJOR strike against your account, and in my opinion you will never fully recover from such a large strike. eBay will be watching that account very closely. One slip-up and it's toast.
This is in no way a fact because of eBay's randomness. But I use to wait 90 days before listing anything that could cause a violation. Sometimes it would reset and start me off with a warning again. Other times it would continue up the scale (example: warning, 3 days, 7 days, 30 days, indefinitely suspended). Others I have sold accounts to have gotten multiple 7 day suspensions before getting a 30 day suspension. I do not know the cause of this.
30 day suspension how long before clear
