The mentioning of the game(s) in the Title/Description of a Wayspot.

Mentioning Pokemon/Ingress/WU in the Title/Description of an unrelated Wayspot is of course ineligible, ie calling the local swing set "The Pikachu Swings" or writing "Enlightenment only" in a description of the local park.
BUT, in several of the Wayfarer groups I'm in people keep claiming that ANY mention of any of the games at all makes the Wayspot ineligible, meaning for example a professional mural with a Gyarados on would not be allowed to mention neither "Gyarados" or "pokemon" anywhere in title/description. Or the Harry Potter movie museum not mentioning "Harry Potter"....
To me this seems ridiculous and obvious, but apparently a lot of people interpreted the rule as meaning "any and all mentions, even if relevant". This can't be right, can it?
Edit: Like, how would you be able to title a mural saying, for example Pokemon Go, with pokestops, gyms, pokemon in it, etc without mentioning any of it. "Colorful Mural of Popular Game" - "Mural by artist xyz painted in 20** to celebrate xxx-anniversary, featuring known items and figures from popular game"? That just sounds weird.

You're right. Only the games themselves (Pokémon Go, Ingress, HPWU) and game-specific terms (portals, hacking, Gyms, Pokéstops, lures etc.) are banned from descriptions and titles. Things like Pokémon the franchise or the specific characters, Harry Potter the literary/cinematic character or Ingress the town in Kent are perfectly acceptable if they're relevant to the PoI itself. The Gyarados mural and the Harry Potter movie museum are great examples of things that should be acceptable.
If the reference is relevant to the POI, such as your example of a Gyrados Mural, then yes that should be acceptable because it is explicitly relevant to the nomination.
However, if an in-game term or franchise reference is made unnecessarily, then that would not only devalue the nomination and the wayspot as a whole but also add a layer of misrepresentation (which could fall under abuse), as the term or reference is not relevant and is taken out of context.

I know Ingress too. So people that created Portals and added Portal to the end of the title likely broke a rule? I have trouble getting things out the description when I see "XM, it's everywhere" or other terms that the usual Pokemon GO player would not recognize. Do you believe the same? I type **** to be any word. **** del portal is findable too often in Ingress Intel Map.
Wollongong, south of my area had many Pokemon Go-themed nominations in their title and description. Things like "Mystic Park" or "Shellharbour Pidgey Club" are some examples. There is even a portal called "Very Rare Heat Sink" in the CBD as well.
If there was a Gyarados mural, then it's completely fine to reference Pokemon. Just not Pokemon Go, because the actual mobile game is irrelevant. If there is a Harry Potter themed mural or nomination, references to Harry Potter is fine, just not Wizards Unite. Etcetera for all games except if it is directly related to a feature in their specific game, like Pokemon Go (i.e. team valor/mystic/instinct or references art from Pokemon Go, etc). Or if there is a backstory that relates to the games such as the Etika mural tribute, that would be alright in my opinion.
But the amount of times I've 1-starred a nomination for "Title or description is not irrelevant" is probably something I've lost count.
This must be why my submission of a dog **** in the middle of the road that I called "enlightened wizard pokemon go to catan" keeps getting rejected.
