My Adobe Stock contributor account has been blocked.

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.

Adobe likely detected suspicious account activity.
1) Unusual sales or refunds.
2) Protected Brand Names in keywords/descriptions.
3) Multiple accounts to artificially boost sales or bypass submission limits.
4) Complaints / 'Take Down Notices' from customers or 3rd parties.
5) Other violation of Stock Contributor Terms. See below.

This matter is solely between you and Adobe Stock, not fellow Contributors in this user-to-user community.

Be patient. It may take several weeks for an investigation to conclude. Check your email spam folder. If requested, provide additional information directly to Adobe Stock. In the meantime, work on other projects. Submit content to other stock services.

Good luck.
