You need a user account to post a review. Just like your first kiss, you only get one user account and it should involve a real person. Your username, profile description and picture must reflect who you are (don't go impersonating other people, thanks) and can't be harmful, hateful, discriminatory, defamatory or obscene - because everyone can see your profile! If you do include something you shouldn't, or you create more than one account, we can delete your account/s.
Your user account also needs to be connected to a valid, permanent email address in case we need to contact you.
Sometimes your account is automatically created and pre-filled with your name, like if you click on an email invitation link from a company or sign up via Facebook. You can always edit your details to include only the information you want publicly displayed.
