Here we go Again. An extremely controversial spot and Niantic is happy with it. Just consider this is not an official placque installed by and local government or city council. It is installed by extreme right followers, usually removed by police, and then re-installed.
Please understand that local community is probably the one reviewing and approved said wayspot. Niantic has long delegate majority of wayspot review to the community. Whoever submit it may/may not realize it as well.i guess whoever handle removal may not realize it as well. you can report abuse to whoever submit it if you believe its done on purpose.
