There are places in other country which is not so convenient to get internet access and they dont feel necessary to open email regularly since most of it just filled with advertisement and spam but they are using Instagram, facebook and other account. Its silly when yahoo INactivated and recycle this email while they still actively using it to login facebook. The problem came when she wants to change Instagram password, since she only can login thru facebook account there's noway to retrieve new password! Yahoo please answer me!!
