i just found this though..not sure how well it works but it might be worth trying for pc users?

I was just messin around with drawball when i decided that i would try to get unlimited ink. I realized that they moniter how much ink that you have by making a TCP/IP account as soon as you enter the site. So, i realized that if you were to change your ip address, then you could easily use as much ink as you want because each time that you changed your ip address, you would log into a different TCP/IP account when you entered the site again. Hence, your ink would be refilled to 15% every time you when onto the site (with the different IP address). I do this now and it works for me. Here is a list of things that will be required:
1. Windows (ME - XP)
2. At least some small amount of computer knowledge
3. A Cable/Broadband connection or DSL connection (as long as it's "always on")
Ok now to change your ip address, do this...
Click on Start > Run and type in cmd. In the command prompt, type this in exactly (with out the quotes), "ipconfig /release". Hit enter. It will then 'shut off' your internet connection. But its ok dont worry! Now go to Network Connections from either the control panel or going to Start > All Programs > Accessories > Communications > Network Connections. Then right click on the Local Area Connection icon and click on Properties.
Now it will open up a new window. in the little list provided, scroll down until you see a value with the title "Internet Protocol (TCP/IP)". Click on it to highlight it and then click on Properties right below it. Click the "Use the following IP Address" bullet and in the ip address field, just type in a random series of 1's and 2's and then once all of the available space is taken, hit TAB and the Subnet Mask field should automatically fill itself in. If it doesnt, then just type in 255.255.255.0 as the mask. Then hit ok at the bottom and then click on close in the next window. Then right click on Local Area Connection again and go to properties (again!) and choose the Internet Protocol (TCP/IP) properties again. Now Click on the "Obtain an IP Address automatically" bullet and then click on "OK" and then close on the next window. After that, your ip address will be changed! You can now go back to drawball and draw again! Although you only have 15% ink, when that runs out, you can just repeat this process over again. It sounds like its a lot of work, but it actually only takes about 30 seconds to do once you do it the first 2 or 3 times. Since this trick changes your IP, you can get around IP ban restrictions, Rapidshare restrictions, and pretty much anything else having to do with ip monitering. Now go show drawball some PBF love!
***NOTE*** If your ink isnt refilled after you do everything in this tutorial, then try deleting all of your cookies. After that, it should work.
***NOTE2*** If this needs to be moved into the old thread I will do so. But I think it's important enough to have it's own thread.
