I once joined a survival PVP server, and started building with someone, then he got more to join, and we become 8 people and built a massive house, found dungeons and stuff. But then, the server updated, and once I got back, only 2 people were left (Which were friends with each other).

So, I wanted a lava fountain as a source of light inside, and I told him to give me the lava bucket, but then he said he would do it himself and put it on the wrong place. Then the whole house burned up, they started killing and spawnkilling me, and blaming everything on me. They said it got destroyed because I told them to put it there, but I told them to give the bucket to me. so they put lava on my spawn, killed me with a stone sword, until I escaped and killed the one with the stone sword and then the unarmed guy. After my victory, they left and I felt quite pissed off. All that work and teamwork, turned into a big, unnecessary fight.

I had learned a lesson, never trust as many people at one time without knowing them, because since you are alone, you are defenseless and they can blame everything on you and will always win if you are outnumbered.

This is my story, about a huge mistake I made.
