At ptwiki, I was trying to monitor changes made to wikidata items on my watchlist https://pt.wikipedia.org/w/index.php?userExpLevel=unregistered&hidepageedits=1&hidenewpages=1&hidecategorization=1&hidelog=1&invert=1&limit=250&days=3&changeType__hideWikibase_color=c2&title=Especial:P%C3%A1ginas_vigiadas&urlversion=2, trying to get only IP edits, but some registered editors are showing up as well.
