Thanks for putting this together!

We should also add a test that exercises ignored users in a comment and a review. Let me know if you would like some help with any of that.

Thank you!!

I've added two test cases for ignoring users. Are they reflected correctly?

[zkoppert]

Thanks for adding the tests! I also debugged locally and confirmed that only 1 comment or review comment was being put into the iterator and when I made the fd029d1 it now has multiple comments in the iterators for checking.

🎉 Thanks for another wonderful contribution!! I'll personally be using this now to exclude bot accounts when I use this action. Much appreciated!
