If I write out the answer to a problem and put it on GitHub, then I can easily win a challenge by simply writing code to fetch the answer. Is this valid? I've never seen it been forbidden in a challenge's rules.

    \$\begingroup\$ The reason you've never seen it forbidden in a challenge's rules is because it's seen as a standard loophole, e.g. loopholes which may be assumed to be closed without the question-setter having to explicitly close them. This particular loophole is listen on our page of standard loopholes as the second highest answer. \$\endgroup\$
