There was a board advertising a neopoints selling site for a long time. It's the hiddentower or something.
I liked the LC. And so did a lot of other people. It was rare for people to not get it at all but I mean it was a challenge. Most of their questions were based off searchable problems/concepts. Not everything should be easy in life.
The point was it was just another feature they took down because they probably fired the guy that made the questions up.
