Constant APPEAL_EVIDENCE_DOC 

pub const APPEAL_EVIDENCE_DOC: &str = "Cite evidence by writing post or comment UUIDs \
     directly in the statement: every one is fetched and put before the court, so there is \
     no separate evidence field and an id you argue from does not need naming twice. At most \
     5, and each must resolve to a real post or comment — removed content counts, and is \
     usually the point. A filing citing something that resolves to nothing is refused rather \
     than adjudicated on inert evidence, and the refusal names every problem at once so you \
     can fix them in one go. You do not need to cite the `moderation_action_id` itself; it is \
     already before the court, and quoting it costs you nothing.";
