Reposting an Instructable for a contest Answered

I do not know whom & how to report this to so i decided to write it down & post it in the forum,
yesterday i was browsing through "make it youth contest entries" & saw someone reposted an instructable to change the date & be able to enter in the contest,look it for yourself

https://www.instructables.com/id/Battle-of-the-Fuels/

He simply changed name & all the content still matches to his other instructable . i would not consider it as a fair practice to repost stuff so you can enter a damn contest
the rest lays in your hand's
