Requirements for (New) Challenges

HTB Content Challenges
1

I recently found the source code of one of the challenges on GitHub and it seems that the challenge was developed a few years ago for some other learn-to-hack project and released under GNU GPLv3.

For machines its a requirement that the machine is exclusive to HTB but I haven’t found the requirements for challenges (yet). Are they the same? Are there others?

Make sure that you haven’t copied your challenge from any other site and you made it yourself.

Should I report the challenge then?
