Description
I'm the creator of Advent of Code. A system similar to this one was recently proposed on Reddit; it makes me nervous for a few reasons which I listed in a reply:
Please don't create a database of inputs. Doing this would make it easy for someone to rip and re-host my work.
Doing a beauty contest, size comparison, etc don't require a common runtime; you can already compare the code of many solutions on the megathreads or even GitHub.
Some puzzles (intentionally) use a lot of CPU or memory, which could make hosting this service expensive.
Without having a human check the submitted source code, there's not a good way to verify that the program doesn't simply print the answer and immediately exit.
Do not duplicate the puzzle descriptions on such a site. Doing so could remove adventofcode.com entirely from users' workflows and effectively steal my work and use it to also steal my traffic. (In fact, I'm already nervous about this even without duplicating puzzle descriptions.)
Basically: I spend hundreds and hundreds of hours building this stuff. Please be careful not to ruin it.
