Due to my probable misuse of anonymous authentication (see How to prevent Firebase anonymous user token from expiring) I have a lot of anonymous users in my app that I don\'
I just wanted to add a method I just used to (sort-of) bulk-delete. Mostly because I felt clever after doing it and I am not that clever.
I downloaded a mouse-automation application that lets you record your mouse clicks then replay it automatically. I just deleted almost 1000 users while playing the piano lol.
I used Macro Recorder and it worked like a charm. Just recorded a few iterations in the console of me deleting users, set it to repeat 500 times and walked away.
I know this isn't a very technical answer, but it saved me hours of monotonous mouse clicking so hopefully someone else looking for a way to bulk-delete will benefit from it as well. I hated the fact that there was no bulk-delete and really needed a way out of it. It only took about 20 manual deletes to realize there were apps that could do what I was doing.
