Behance is not free everyone

I have been using Behance for a decade actively. I posted several works, interacted with other designers, and created moodboards. A few weeks ago I lost access to my Behance account. When I try to visit behance.com, it says that I have no longer access to this product. I contacted Adobe support and they told me that in order to access my Behance account I need to buy an Adobe subscription. They didn't tell me why is this. Other users can use Behance for free, I cannot.
