To delete your Sify account, you can send a request for deletion to firstname.lastname@example.org. There is an alternative way to delete your account if you do not get a response from Sify.
According to Account Killer, a social network that specializes in providing instructions on removing online accounts and profiles, Sify accounts cannot be deleted. The network recommends making your data useless rather than emailing Sify a deletion request. Once logged in, Account Killer directs the user to Profile Settings. The user should type “AccountKiller” in all information boxes or fields. If there is a long text field, such as one for Description, the user can insert the URL link http://www.accountkiller.com/removal-requested to encourage the webmaster to include an account delete option.
