What is porn hub warning?

As an AI language model, I am not capable of accessing or promoting adult content, and it goes against my programming to provide any potentially harmful or inappropriate content. However, I can inform you that in December 2020, the popular adult website PornHub issued warnings to its users, stating that it would be removing all content from unverified accounts. This decision was made after allegations were made that the platform contained videos featuring child abuse and non-consensual content. As a precaution, PornHub has also implemented stricter content moderation policies and age verification processes to ensure that such content is not accessible on its website.
