The secret behind mm2

I was playing some mm2 with my friends and then a guy wearing exactly what i was wearing in roblox but only with the decay face on joined. My friends and i looked at his inventory and we saw most of the old godly like crescendo and ice dragon but the only difference was that the knives were named GET HACKED and DIE_PLAYERS. We got scared and soon left the game to go into knife opener (sandbox mode for mm2). We went in and we looked at the knives that the roblox user had and they were also called the names. We thought that user was a new hacker and we soon found out that he wasn't only a hacker for roblox, he was a hacker for multiple games on iOS and other game industries. We stopped for a little then went back and everything was back to normal. But whenever i would go into a game i had the decay face on and my skin was completely red and i lost everything in my inventory. I went back onto mm2 and i found out that there was a code to type in on a wall and for a knife. The code on the wall was 13629243826 and the code for the knife was HACK3R in all caps. The knife you get is a godly and what i thought was that it had to be a hacker because mm2 would never put a godly code and hats a fact. I used it for a little until i checked the sources for the knife and it showed the code for the wall so i typed it in and there he was standing there as a black figure then my game crashed and i was never able to play mm2 or its sandbox version ever again. I soon call my friend about the incident and he did it and the same thing happened and thats the dark secret to mm2.
