fake-ness confirmation?

so yea, i saw this on another forum (this is the whole post, and also the only post the poster made about the sword):

It is the most powerful sword in game AT THE MOMENT because

 Spoiler

the reasons i think its fake:
1. i never read anything about such lvl maple weapons being released in any version
2. the basic attack wouldnt make any sense compared to other maple items or normal swords
3. the post has no actual source added, only a vague discription of where he got it, not trackable
4. the picture is kind of blurry
5. the story of a guy getting gm blessed and with that finding an item sounds kinda bullshyty


so yea, i promised a friend i'd search for info to confirm if this was a fake or not. any of you guys know more about this item or is it what i expect it to be



p.s. after watching it again i came to a conclusion, that i think is evidence enought to prove this a fake:
the weapon does not have pirate job as an option added to the job list, + its english language, which means its eithe a maplesea or gms screenshot. neither of those have the sword in the data so yea
