Item Duplication

I have bad internet so sometimes my client gets disconected from the server, I join right when i get disconected i see my self leave just as the other players but then im still in the server again and can play. sometimes it happens more times and i can see my self in the server before i leave, i tried to kill myself and it worked but then i can grab the items that i dropped even when i killed myself it says B_Scipio was Slain by B_Scipio. and then i just dubplicated my items, I report it because i dont people to take adventage of it.
