title: Firestore limit reads and writes per hour or per day to prevent user setting a timer in the inspector
body: <p>I am learning Firebase and I might use it in production. I can not find how to prevent a logged in user to edit javascript code and trigger thousands of reads per day automatically and that I will have to pay for. As far as I know, any user who would like to increase my firebase bill could set a timer by editing javascript code and read and write every 4 seconds where he can in the firestore database. How can you prevent a user read rate per day or hour? </p>
