If someone drops an item and doesn't mention "Don't pick it up" or anything like that and I pick it up is it against the rules in anyway? Cause this happened and he started saying "WTF...", then I dropped it feeling sorry for him and someone else picks it up...
Then he threatens to report us all.. Did I do anything wrong? Did I violate any rules?Thank you in advance to reading and answering this.

it depends on conditions.
