I logged in to my account after 3 years and it shows account suspended message. I don't have any notification or email explaning the reason. Could you please review the account?
You can reply their ticket as soon as possible and comply with the terms and conditions. But first try to find out why they suspend your account and then discuss about it. Again if they suspend your account first time, then you will get back your account. Remember some common and serious violation on upwork.
