Saw it just now: When I accessed https://en.wikipedia.org/w/index.php?title=Special:Search&go=Go&search=mw%3AAPI%3AAccount%20creation , [[Special:AbuseFilter]] was shown. A reload made it go away (to have me redirected). No known way to reproduce it.
This happened just now, at https://ne.wikipedia.org/wiki/?country=NP&uselang=ne&force=1 , but the resulting page is [[Special:AbuseFilter]] again.
Sorry but it happened once again, at https://ar.wikiquote.org/ and still [[Special:AbuseFilter]].
