Some like to hide in a vase, use the red tearing ring, have low health, the crown of dusk and the bellowing dragon ring to maximize the magical damage of a spell.
Had some months ago a hiding in the pot fight with a japanese guy. It was late at night and we were the only ones around in upper Blighttown. Both of us were trying to trick the other one - he invaded again and again and I had a nice chat with him.
At that time I learned about many cool hiding places in Blighttown. Trust me, if you hide in chameleon form in upper Blighttown and you know the best spots (which are quite difficult to reach) then you can leave the console on over night and read some furious messages the next morning.
