Product copyrights manipulation (50$)

Product copyrights manipulation (50$) Hello! Thank you for having interest in this topic. I'm in project manipulating, millions of e-commerce products daily. I can not describe about it specificly. But when you process millions of products on internet, there are some instances that having issues with copyright law. Originally, If it's having copyright issue, of course I don't wanna use it. I'm not willing to. But the process procedure actually is alot of work. It's really hard to filter out which one is having which copyright problem properly. And I'm pretty sure some people have gone through the same difficult process. About this Copyright controlls. So here I am asking questions. Question 1. Is there any place that collected copyright-related contents or products lists around any online websites? so I can match and inspect if one of my millions of product is among the list? Question 2. When you're sourcing the product from online, what's the way to avoid / defense this copyright problems? Question 3. Is there a way not losing opportunity of millions of products manipulation while not having proper shield against this copyright strike? Thank you for reading! Have a good day and bid me if you think you can complete it. Anytime ! And I am willing to respond very quickly to explain more what I exactly need. also, if you can really make it out well this time in this project, I will promise to carry out further projects with you. Thanks alot.
