I found myself, or rather my google account added to a similar google files "thing". Apparently, all someone needs to add you is your accurate Google Email or registered email. They don't even need to know you. I tried to complain to Google but shockingly, they are really hard to get hold of in my country. I kept removing myself from having access but whoever was in charge soon revoked my rights under admin powers. I kept reporting them over and over and eventually it stopped. Google is one of the worst companies in the world, by worst I mean evil. But also, arguably too big to stop. This makes me sad. A friend once told me, "It's a shame this world has over 3000 trillionaires and each one decided to be Lex Luthor instead of Batman 😢
