Someone has been causing me trouble, and I challenge them to a duel

First off, as for why I'm doing this on an alt, long story short, the community glitched and became invisible in ML, and I spent maybe a few hours trying to find an instance where I can get to the point without the application process.

I am as my name suggests and I guess I'll be the first person here to challenge a duel. In a world where they can prevent acts of terror, in a world where they can serve as piecemeal war without much tragedy, in a world where it serves as a substitute for something which would amount to escalation and for faulty due process (cough cough kangaroo karmacourt cough cough), in a world where they probably want me out too, and in a world where the person I am challenging is willing to engage in actual threats against his targets (in that case it's not me he's targeting but the person he keeps conflating with me), let's see if we can settle this the good, bad, and ugly way. This duel will still be valid in archived form and will count as a redeclaration any time it is linked to until the duel is dealt with.

I know this person (and their squad) isn't outside the reach of this challenge (or its effects), they have been spying on and trying to affect this other victim (one of them anyways) of theirs whom they (the person causing the trouble) has been trying to get banned from as many places as possible under wrongful, authoritarian pretenses, sometimes even engaging in the kind of deception that would wreak of suspicion (such as, in that case, where someone with no account activity claims to be the friend of someone who he accuses his main target of impersonating when it wasn't even her who showed any pictures, not that it isn't telling that such a person just miraculously happened to be available to comment) if not for the fact he knows how to pull on peoples' stupid strings (with him supposedly accusing me of being his main target because she and I share some expressive traits (I would be banned if I was her due to her being banned from the places I say things), not that the effing US president doesn't share them too for the same reason we do).

Here is how this is going to work. You have two weeks to acknowledge this challenge and its terms, and any rejection must coincide with backing off with your demeanor and your threats or you will experience incomprehensible pushback, while agreeing to the duel must entail you agreeing to the terms. This should not be outside of your abilities or understanding as it was the community you claim to fight for who also challenged your main victim to a duel.

The terms:

The duel, which will be between you and me, must be one of these (of your choosing): A RuneScape battle, a Mario Kart 8 race, an art contest with the winner decided based on a vote, a real life sorcery duel, or an actual traditional duel.
If you win, I will be out of the picture forever, and with your main target's permission, so will she. If I/we win, you must make a public statement clarifying that all the damning things you said about us were false.
Nobody can call off the duel once it has begun. It will be enforced by the people and the administrators.

Come forward all who have questions. The other victim, the main one, can answer questions too.
