That's a question you will have to ask ebay. It depends on what the length of your suspension is, what you did, the background story, etc., etc.

 

Some members here will scream "NO! YOU WILL NEVER BE REINSTATED!" right away and they will give examples of themselves and their friends. But nobody can know such things.

It depends on what the suspension was for?

Ebay will actually let you know for how long for example 7 days or permanently suspended.

If ebay gives you a reply along the lines of that you have made a buyers experience on ebay a unsafe experience then you can kiss 

selling on ebay again.

Thank you all for your replies. I’m don’t think they ever used the word permanently but they didn’t give a time frame either

When it happened I chatted to a really rude and unhelpful eBay consultant who said why are you asking for help now, what have you have done nothing to improve. I can’t and won’t help you and ended the conversation. I then rang eBay and told them I think I made mistakes which got me here. What happened was I sold plants, and not always ones I grew. Sometimes I’d buy them and list that night. What looked good at the start of the listing didn’t always look great when it ended, not to my standards anyway so I’d let the customer know and and cancel the order choosing the option out of stock even though I had it. The representative put me through to a supervisor and he looked at the one listing he could because it wasn’t over 90 days, he decided to remove it which then brought me above average
