@zleap It means people who actually use the service.
I have opened a discussion in our Staff forum requesting that we consider deleting old, never active, not a single post in their lives accounts.
As in -- what are they good for? Contribution, imo is less than Zero, as their user addition costs some storage Bytes in the server storage. I am tired of seeing the inflated numbers, and would have regular pruning in place (common in many Forums I have been a member and staff on, all over the internet).
These inflated, unrealistic figures, are good for Ego reasons, in some cases; look how big my server is! 😜
