Well I cheated by using FireFox and GreaseMonkey. I had to change something to make it think that Plus! was accessing the site before going into entrance.php and not FF and then my greasemonkey script just replaced a cookie, and select a random position on the grid, it then checked to see if it had already been chosen and would select a new one until it hadnt been chosen. After it found one then it would send the coordinates and check if the page had the "try again" box (or something like that) and if it did then it would wait a random amount of time (between 1.5 and 3 second i think) before it would try again.
It had lots of random stuff to make it harder for Patchou to detect
