If you really wanted to cheat the system you could try these two methods:
blackhatworld.com/blackhat-seo/freebies-giveaways/579586-free-500-brand-new-reddit-accounts-june-22nd-23rd.html here is just under 1,000 reddit accounts.
hidemyass.com/proxy-list/ here's the largest proxy list in the whole world.
whatismyipaddress.com/using-proxies Here's how to connect to a proxy.
If you knew what you were doing I don't see why you couldn't give yourself 1,000 reddit up votes, since you'll have a new IP address every time. I would suggest doing it in private/incongnito mode, as Reddit puts cookies on your computer. That means every 10 or so upvotes just close the browser and reopen in incongnito/private mode and it should work as those cookies will be gone and you can continue.
I haven't tried it, but I don't see why it wouldn't work and with 1,000 reddit accounts you could get on the front page (potentially).
