What does Adobe Stock do with the work of a contributor that decides to leave the platform?

In the Adobe Stock Contributor Agreement, it is stated that a contributor "Grants them (the company) a non-exclusive, worldwide, perpetual, fully-paid, and royalty-free license to use, reproduce, publicly display, publicly perfom, distribute, index, translate, and modify the Work for the purposes of operating the Website, presenting, distributing, marketing, promoting, and licensing the Work to users; developing new features and services; archiving the Work; and protecting the Work."

The document defines "Work(s) as the content created by a contributor that they submit to the platform, including descriptions, credits, captions, etc.

My question is, What does Adobe Stock do with the Work of a contributor that decides to no longer upload their designs and leaves the platform or deletes their contributor account. Does the word "perpetual" mean that Adobe Stock can reserve the right to continue to display and distribute their work after a contributor leaves? Does Adobe Stock archive the contributor's content in their servers or permanently delete them?

I am not a contributor, but I am considering the idea of doing it, and this question just popped up in my mind. 

Hopefully someone can anwer. Have a good day y'all.
