Step 1) Spam the crap out of the Digg user comments using multiple accounts, multiple URLs, and make them all look like legitimate links. Continue this for a few days, to get people good-and-angry.
Step 2) Post a story calling for your own spammy, fake, accounts to be IP-banned. Everyone blindly insta-diggs it, because they’re really pissed off.
Step 3) Profit.
Seriously, read the comments and watch the diggers slowly realize what’s just happened. I don’t think there’s anything funnier on the Internet.
