WhatsApp may soon be launching it newer version which will allow you to set who can Invite you to their group. It is always annoying when you are being invited by someone to their group where you actually don't want to be. Its even more annoying when you are invited to some group and you can't leave just because you need to answer them why you left, funny but true.
