I know this seems obvious but idk why it's hot here, no moderator or admin will ask for you're Gmail account. If they say something like " I can have to you free gems I work with igg" don't. Just don't give you're password to anyone. And don't buy accounts if someone " quits" . You can easily get scammed on the Internet.
Also if you find a " Gem generator" it'll probably ask for you're account or something or make you download a program. There's no such thing as a " Gem generator" it's a scam and you'll probably get a virus on you're computer or android
