I tot there is always new member register monthly since few years ago. But data from nov 2017, show almost consistent number of visitor which is 6 million per month. Means number of actual members not growing. No of visitor not growing up with no of new registration. This scenario not worrying to u ke in case one by one people left k forum one day since new members not growing.

I believe new registration mostly dupe. Yeah, people can have multiple dupe, but when they online, they only use one account, which explain why no of visitor is consistent since nov 2017.
