If we assume spammers will churn through $5 domains in very high volume, and notice if any of them get expired by BL maintainers, so they all need to stay in BLs, how big a BL are we talking about?


  Something significantly smaller, IMHO -- otherwise the registrars
would get filthy rich. ;^) Spammers are nothing if not cheap.
 From http://www.dailychanges.com/:
Changes are being tracked for (.COM, .NET, .ORG, .INFO, .BIZ, .US, .WS)
Today's Date 5/13/2004 9:51 AM PST

Status of domains on 5/13/2004
All           38,977,593   Total Domains
28,306,930       .COM
4,656,800        .NET
2,942,751      .ORG
1,161,175           .INFO
979,265           .BIZ
769,034              .US
So, let's wild guesstimate 100 million domains worldwide, ~18 bytes long, half are spammers.
900 million bytes, uncompressed.

Reality check: could half be spammers'? That's $5 * 50 million. They don't have that much cash.

Stolen credit cards.
