Please don't send it to Sidelines. Sidelines doesn't collect anything, on purpose, so there's nothing here to leak, hack or hand over. If you have information a journalist needs and you need to stay anonymous, use SecureDrop: the whistleblower system Aaron Swartz began building, now maintained and independently audited by the Freedom of the Press Foundation. Many newsrooms run their own SecureDrop.
