This is a pirate site at it's core. That is, sharing paid content for free. If someone shared the paid version that was intentional, in fact, encouraged. The person did so by sharing it with uploaders/moderators who in turn modified the original post accordingly. When this is done in this manner, the source does not just drop the links in a public post, his identity remains anonymous and will remain so. The staff will not reveal it unless he or she explicitly wishes so.
Again. Sharing such paid content is the deal here. It will not be removed and the practice will continue in the future as well.
You may as well discuss with Staff members but the answer will be the same. In fact, i do encourage to reach out to them to discuss the matter personally and read it from officials instead of just asking from random members. Use Tickets.
