I've been trying to disclose a vulnerability in Instagram's support process that is being widely abused (social engineering). Unfortunately I can't get their support or press team to respond. FB White Hat disclosure did respond but can't do anything unless it's a technical exploit. They have flaws in their account recovery mechanism.

It's a long shot and perhaps the wrong place to ask. But. Does anyone know someone at IG I can contact to disclose this issue responsibly?

Thank you.
