Help me to reactivate my blocked account

Depending on what triggered the account block, it may take weeks or months for an investigation to conclude. 

In the meantime, work on other projects & submit to other services. 

Nobody in this user-to-user community can help you. This is a private matter between you and Stock Contributor Support.  Good luck. 

I do not want to scare you, but I still wait for resolution of the appeal. It is nearly 7 months already...

How to Report (and Appeal) | Adobe Transparency Center

If your account has been suspended, there is nothing that this community of peers can do for you. You will need to contact Adobe contributor support via the link at “Contact us”. Adobe will answer via e-mail, so watch your spam folder. The answer may take some time, depending on the workload of contributor support and the complexity of the investigation. So be patient and do not spam the contributor support.

There's really nothing else you can do accept wait for a response.

If you used the Contact us link that you see when you attempt to access your dashboard, you've done everything you can do. Do not send follow-up emails, as it potentially creates new tickets and can slow down an already slow investigation process.
