Adobe Stock restricts my contributor account without any justification or reason

Adobe likely detected some suspicious account activity.
1) Unusual sales or refunds.
2) Use of protected Brand Names in keywords/descriptions.
3) Content spamming or using multiple user accounts
4) Complaints / 'Take Down Notices' from customers or 3rd parties.
5) Other violation of Stock Contributor Terms. See below.

Contact Stock Contributor Support: https://contributor.stock.adobe.com/contact

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 audit to conclude. Check your email spam folder. If requested, provide additional information directly to Adobe Stock.

Meanwhile, work on other projects. Submit content to other stock services.

Good luck.

Use the "Contact" link you are provided.

You are not addressing Adobe here but contributors like yourself, and we are unable to be of assistance. Use the "Contact us" link to ask for details and wait for a response if you have not already done so. It will most likely be awhile before you hear from them, other than a possible generic email notifying you that your email has been received. Keep an eye on your junk or spam folder if necessary. Do not attempt to contact Adobe repeatedly, as doing so can potentially slow down Adobe's investigation.
