Hello @LGi90
I know this is coming as a shock to you and your local community, but Niantic over the last few months has been reviewing clusters like this because of the wayspot placement abuse.
Note that each Niantic game has access to the Lightship database where all the accepted wayspots are stored. Then the games select from it to populate their game boards based on their inclusion rules. So the manipulation in the past broke a bunch of those rules.
Please see the article here for another such case: Massive disappearance of valid Wayspots (Częstochowa, Poland)
