I have been receiving emails from Gree advertising various Gree games and I did not sign up for these emails.
Unsolicited spam email is illegal in my country. Just FYI, Gree, you guys are illegally spamming my inbox with unsolicited advertisements. Perhaps it is unintentional, I certainly hope so, but maybe someone should look into it before you get into trouble over it.
You're welcome for the heads up.
