A rake button gets added in every post, /qb/- Quebec is created, a counter on how many canadians there are on a given board shows up (some speculate this number was autogenerated), and flags were removed from every board that had them. A user could click on the rake to report canadians to 'deport' to /qb/, although a warning before doing so warned that false reports will result in deportation as well. /qb/ was a red board with no topic with every post having a canadian flag, that had the anthem of Canada sounding in the background.

The captcha is very occasionally replaced with a prompt with a picture of an anime character which asks who it is, or asks a question about oldfag 4cuck culture. At least it didn't make every board anyphono cared about completely unusable for the day.
