Linlin is touted as having the best web of information in the world.
Marco realized it due to Whitebeard and fighting him for 30+ minutes.
Queen knew probably because of Kaido.
I think, logically, the WG should know. But the fact King is hiding his race and his face 24/7 so nobody knows tells me there’s a reason for it. And IMO the only reason King has to hide is face is to deceive the WG.
The wg likely knows but not every single person apart of it since how long back kaido and king left punk hazard
Like the wg obviously know's about rocks but not everyone with ties with the wg does. Or like germa being real etc
When it comes to linlin true but the world government should be even better
Marco not fully realizing at first makes sense with how uncommon lunarians are and with marco and king seemingly not interacting much before onigashima
I don't think kaido would be telling people information king clearly doesn't want everyone to know but i could be wrong. I imagine either queen could tell either by looking at him and his abilities or him and king are surprisingly close lol.
Also didn't queen use to work in punk hazard? He could have known them since
