how did u do to block him?
there are software which can 'sniff' mac or ip addresses, but you
can easily achieve that with the available tools windows os

- First, if he uses the same ip address as yours, your os wld send

- Second, cloning mac address could be the cause. You can find out
by changing ur mac-address. Just remember to jot down the original
value before the change.
Bandwidth all to himself? Nt that i know of. Maybe to an extension
where ur connection becomes very slow.
