Leaving a comment to add visibility.
Already expressed the same concern and linked several spoofers’ posts from Threads in previous post about Taiwanese spoofers.
They have many groups/chats sharing mushrooms’ and Big Flowers’ coordinates. It’s really insane how publicly and shamelessly they are when discussing spoofing on social media. Pikmin Bloom has an official Threads account and I bet they can easily find many spoofers’ posts but they did absolutely nothing and condoned such behavior.
At first it was due to an influx of new players joining Pikmin Bloom and many players complaining about not being able to join mushroom battles. Then a few months ago, Niantic added a bunch of new mushroom locations and they are still complaining about the postcards aren’t “good looking” or they are spoofing for rare mushrooms like elemental or large shrooms… the greed just never ends
They are truly obnoxious and even Japanese players posted about it just a few days ago…
