Research:Daily edits by anonymous users
Using IP as an identifier
The current metric depends on counting IP addresses within the specified period as a proxy for distinct anonymous editors. A unique IP address doesn't necessarily identify a unique user due to IP rotation, IP addresses shared among multiple editors, proxies etc.
As this is a daily metric, a full 24 hours must elapse after the beginning of the date (UTC) in order to calculate an uncensored value.
Edits on deleted pages
This metric includes edits on existing pages as well as pages that have been or will later be deleted. This allows us to define a metric as stateless, in other words historical values will not change in the future depending on the status of a page (existing/deleted/moved) at the time the metric is computed. Deletion-related activity is tracked via a separate set of metrics.
Edits across all namespaces
This metric counts activity across all namespaces of a project: whether an edit is a new page creation, a revision to an existing page or a draft, a message left on a talk page or a contribution to a Wikiproject, the edit is counted as a contribution to the project. The metrics is agnostic about the quality, size or purpose of the edit. Specific types of contribution are measured via dedicated metrics or breakdowns.
