I was briefly hacked! I have used this account plenty on my school chromebook. My school district likes to test new browser extensions (Blockers, teacher screensharers) on random groups of students, and I was one of them. For whatever reason, they installed something that happened to track your passwords and what do you know, they got rid of the extension and my account had been remotely signed in to. At least this is what I think happened. The problem wasn't solved until I had reset my password.
I was legit getting scared that I got ip banned or something anyway I'm making a new game
