KILLED AND LOST MY NETHERITE SWORD

this one guy called washingmachine i think he killed me with lava and took my netherite sword and my crazy ass pickaxe. i was afk so like i didnt see thought but when i came back to my screen it said i died because i was burnt to death and  a bunch of other people know. like this dude names NIRU04 or something and this dude called BaDAM and another reason i think it was him is cuz when BadAM was dropping me my stuff when i died he was like right beside me trying to pick it up so please do something about this

We checked your last death location and found that NIRU03 was the player who placed the lava and killed you, along with BadDAM. We have returned one pickaxe and your netherite sword, but we cannot restore all the other items you lost. Both players have been banned for breaking the rules.
