Hi, could someone please how can I get a full list of instagram usernames with their contact email?

Do you think it is possible? 
There is the profile directory but it only shows like 100k profiles.

I saw it is possible to scrap some info with pyton by uploading a .txt of the usernames but I cannot find the full list of usernames.
Can someone help? 

Is there any leak from the past about instagram?

Thanks in advance.

Send me please
