All servers on the Stats page sums the servers that left privacy.includeInGlobalStats on. A number is published only when at least five servers contributed to it and only for metrics that are marked publishable; everything else stays hidden rather than being shown small. Published values are rounded to the nearest ten.
Turning privacy.includeInGlobalStats off removes this server from every global number immediately; its own This server view keeps working. Nothing in the global view can be traced back to a server, a channel or a member.
