Based on the information provided being contradictory with itself, and omitting things that were at that time plainly visible on the site. Also, there were comments restored against my will from years ago, which were not contained in the data dump, even though others were. Which means that Reddit holds data in other places (otherwise they would have been unable to restore that), but have not detailed them in the GDPR request, which means that they have answered dishonestly and incomplete.
