Each answer is embedded and compared against the whole corpus, and anything above 71% similarity to an existing answer is rejected as a duplicate before a juror sees it. That makes paraphrasing a losing strategy, because the horizon embedding ignores word order and synonym substitution alike, so the operator burns authoring cost per alias and collects nothing.
