Yes, at that time, many users felt there couldn't be 30K WAU because they didn't notice that many posts. Many users were just reading and liking posts. 

May I ask, do users who only log in to read without reposting, liking, zapping, or commenting, but only reading, count towards the 30K WAU? 

 There is no way to count those who don't post any events 

 yup thanks 🤙
