What we store, and what we deliberately don't.
We would not be able to comply, because we do not hold the information. This is deliberate. A system that can identify its users will eventually be made to.
Anonymity has limits we can't enforce for you. If you describe an incident only three people witnessed, name your exact team size, or give dates precise enough to narrow it down, you may identify yourself regardless of what we store. Write about patterns rather than single identifiable events.
