Is it possible to get the user's uid without going to his page?

Question

Classmates

You need to get data on the order of 1 million users, but if you go to the pages after 100-200 requests, it runs into flood protection.
Is there a way to take uid other than parsing from groups?

Answer 1

It's good that there is flood protection... A counter question - why did you need so many other people's uids?

Answer 2

Obviously, to compile the base on which targeting will be conducted.
