How this page was made

The rules come from the arctic-shift public mirror's copy of the room's rules list, sidebar and posting guidelines. We do not use the Reddit API. The posting answer rests on the room's own words when they say anything about promotion, then on removals we counted, then on our inference, and the line under each answer says which. A rule that was rewritten after the mirror's copy was taken will not show here, which is why the capture date is printed above.
