1) We found the transaction to be suspicious through our own internal due diligence
2) We reached out to you to give you a chance to verify your identity via email or talk to us on the phone
3) You refused to verify your identity or even talk to us on the phone about the situation
5) You subsequently vandalized our AngelList page.

You are fully capable of requesting that your bank reverse the ACH transaction(http://banking.about.com/od/howtobank/a/ach-payment-fixes.htm). We will not initiate a new transaction because that puts us, and thereby all of our users, at risk of being scammed.
To be specific if we initiate an ACH transfer to you to refund the money you deposited, you can subsequently reverse the transaction that you initiated.

I would like to see you get your money back. I would be more than happy to walk you through the ACH reversal process over the phone. You know how to reach us.
