Unfortunately, nobody here can help you as we don't work for Adobe Stock.

Good luck!

Click the "Contact us" link and ask your questions there. We can't help here in no way. And Adobe will not publicly discuss here, what they were using for making their decision. The block people, when they think that you have violated your contributor agreement. 

Adobe will send you an answer by e-mail, so be sure to watch your spam.

You should contact support and ask them what is the problem. You may be blocked forever, or there may be something you can fix or explain. Adobe have zero tolerance for some things, which is only right, like copying other people's work or generating fake sales - but of course we don't know the problem; it could be done thing simple like needed an updated tax form.
