Just because you are too stupid to be able to stop me screwing you over
with a possession doesn't mean that it's not possible to avoid having
what happened to you happen.
Obviously i'm not going to be helping you out by spelling out how to
defend against what i did but i'm sure if anyone who understands the
skills involved thinks about it, they'll see that whilst it might
be slightly unbalanced, anyone competent would not have suffered in
the manner you did.
