There have also been articles with dead links that are not in the dead links category for some reason.
The WCA records are now outdated; they go up to 2015 and we are in the year 2017.
So I really think we should clean this place, though there would be so much work... and there are also more puzzles not yet mentioned on this site (ie. Dogic Puzzles)... this is going to take a long time. So please answer, should we clean the wiki?
