Technically none of the USERs are on there. USER1, 3, and 4, aren't on the Wiki either (at least in the cast part). Pareidolia and HOPE aren't linked on the Wiki to the USERs or gods that they probably are. (Pareidolia's first appearance is listed as an Event from Chapter 3, even though it actually appeared back in Chapter 1. It just didn't go by Pareidolia until way later. HOPE also has basically nothing on it's page.)
It is a free resource though, and trying to be spoiler free, so it's understandable that not everything is on it. Especially the more complicated supernatural stuff. It's useful even if it's lacking.
Three?:
HOPEburger, Pareidoliaburger, USER2burger....?
Kaori-ness intensifies.
