A company page carried a sentence about its living CEO, lifted almost verbatim from a press kit: called an early pioneer of the sector. Nobody had sourced it. Somebody had tagged it citation needed eighteen months earlier, and there it sat, waiting its turn behind a long queue of the encyclopedia's other unsourced claims.
Then, on an ordinary Tuesday, it was gone. Not tagged again, not moved to a talk page for discussion, simply removed, in the same edit that flagged it. The client wrote in confused: elsewhere on the page, a paragraph about the company's founding had carried the same tag for two years and nobody had touched it. Why did this one disappear in a day?
Contentious material about a living person that is unsourced or poorly sourced should be removed immediately, and the burden of proof lies with the person seeking to include it, not the person seeking to remove it.
The company's founding date can wait for a citation, because getting it wrong costs the encyclopedia a small, correctable error. A flattering but unsupported claim about a named, living person costs something else if it turns out to be false or exaggerated: the page becomes a source other outlets treat as fact, and the person it describes cannot correct it, because they are not the one holding the pen. The ordinary patience Wikipedia extends to a citation needed tag was never extended to that kind of sentence.
What counts as contentious is decided by whoever reads it, not by whoever wrote it with the best of intentions. A founder-approved biography, a birthplace pulled from an old interview, a job title carried over from a five-year-old page, all of it can be removed the moment somebody notices it lacks a source, and nobody owes the page a warning first.
So for a living subject, we no longer write anything on the assumption we will source it later. Every sentence about a named person gets its citation at the moment it is drafted, or it does not go in the draft at all. The tag was never a place to park a claim. For a living person, it was never even offered.
