text: 2. Act normal
  If you are a high-risk source, avoid saying anything or doing anything after submitting which might promote suspicion. In particular, you should try to stick to your normal routine and behaviour.
  3. Remove traces of your submission
  If you are a high-risk source and the computer you prepared your submission on, or uploaded it from, could subsequently be audited in an investigation, we recommend that you format and dispose of the computer hard drive and any other storage media you used.
  In particular, hard drives retain data after formatting which may be visible to a digital forensics team and flash media (USB sticks, memory cards and SSD drives) retain data even after a secure erasure. If you used flash media to store sensitive data, it is important to destroy the media.
  If you do this and are a high-risk source you should make sure there are no traces of the clean-up, since such traces themselves may draw suspicion.
  4. If you face legal action
  If a legal action is brought against you as a result of your submission, there are organisations that may help you. The Courage Foundation is an international organisation dedicated to the protection of journalistic sources. You can find more details at https://www.couragefound.org.
