Here's what happened:
ExpertGamer said "do /warp stoneplace"
I was like "Sure, why not?"
When I came there, he placed lava under me and I died, he also took some items saying "I don't have them"
here are some screenies I took:
http://www.kaise123.com/imgupload/en (http://www.kaise123.com/imgupload/en) (you can see ultra saying that expert almost burned him)
http://www.kaise123.com/imgupload/ez (http://www.kaise123.com/imgupload/ez) (saying he saw only 2 of items so he can take the other ones)
http://www.kaise123.com/imgupload/eW (http://www.kaise123.com/imgupload/eW) (He thought I meant he need to pay me so I won't report it xD, well, bad way to avoid it)
You need to be more careful in the future, However I'm getting very close to issuing a tempban on Expertgamer. He causes a lot of trouble on the server...
