Almost certainly the latter, but I bet if you ask them, they'd tell you 
exactly how they detected it.  That user does reply to changeset 
discussion comments.

Overpass is a pretty good way of finding "what tags were in use at some 
point in the past".  In this case, https://overpass-turbo.eu/s/159K - 
and you can change the date there to look at different times of course.

In this particular case, that depends on whether the community thinks 
that "webpage" is an exact synonym for "website" or not. This list is 
probably the best place to discuss that.  Language is also going to be a 
factor - in Dutch I'd use "webpagina" for webpage/website in English; in 
German I'd use "Webseite" (actual Dutch or German people please feel 
free to disagree here of course).

That's a bit of a stretch, to be honest.  According to 
https://taginfo.openstreetmap.org/keys/webpage#chronology , it never got 
above 150 uses worldwide, and that was a "blip" in 2013.  If you try 
different dates in a query such as https://overpass-turbo.eu/s/159L 
you'll see that usage was always very localised - someone would add lots 
of POIs with the tag here, or there.
