Ingredients:
10 IP Addresses
10 Email Addresses

1. Go to DIGG.com from IP address #1 and register on DIGG.com with email address
#1.
2. Repeat 1 for all 10 IPs and email addresses, never repeat an IP or email address.
3. Login from all 10 IPs and find a victim post.
4. Mark Post as SPAM.

OPTIONAL
5. Find all DIGG articles from your competition and repeat steps 3 and 4.

RESULT
All articles from target site will be removed from DIGG.  After a few articles are marked as SPAM, the entire URL will be banned by DIGG.

NOTES
You may be able to get away with less IP addresses.  5 (or fewer) will probably be enough but 10 is guaranteed not to get caught by DIGG’s filters.
