Hello,
I have done something similar in the pas, but I think you don't know what it takes to do what you want.
The problem is not the program/code. The problem is that you need multiple IP addresses via proxy servers and a good server with sufficient bandwidth. I can help you with all the steps needed to achieve it. But be prepared that depending on the scale you need it, this migh cost a significant amount of money. Also please be warry that this has high chances of banning your account.
If you understand all of the above ping me on the chat to discuss the details.
