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 investigation to conclude. Check your email spam folder. If requested, provide additional information directly to Adobe Stock. Work on other projects. Submit content to other stock services.

Good luck.

If the first account was deactivated for serious violations of the T&C's, it's possible that you are permanently banned from Adobe Stock. Don't waste your time trying to start a new account until you receive the final determination from Adobe. Did you use the Contact Us link in your account to reach out to Adobe?   

"I had uploaded 22,000 files to that account."

I suspect this is the reason your account was deactivated. 22,000 assets in five months? Perhaps spamming with unedited AI assets? In any case, there is nothin we can do for you. You were given a Contact Us link. Responding to it to ask for further details is your only option.
