User:Fuzheado/Sleeper sockpuppets

There are many indications Wikipedia is rife with sleeper sock puppet accounts. Many usernames are created daily, but only a fraction of them have any contributions in the hour after they are created. Actually, most have no contributons even after days. Anyone doing RC patrol since Septemer knows many vandal accounts are of these type.

There are several reasons for this:
 * New semi-protection (Nov 2006) - prevents editing by IP accounts and "new" accounts (usually < 3 day sold), so sock puppet accounts are "aging in the barrel"
 * New throttling of creating accounts (Dec-Jan 2006) - since it's harder to create a flood of accounts, they are being created slowly over time

Evidence
Consider a recent spurt of vandal edits to the article Wikipedia (January 12, 2006)

Each time, the whole article text was replaced with "Jumbo Wheeels!!!!", a reference to a famous troll.

Looking at the creation dates of these accounts, we find:

Work needed
There is not a good understanding of this phenomena. User:Fuzheado believes there are tens of thousands of sleeper accounts on en:, and likely more than 100,000. The problem is that official statistics do not help in tracking this.

Looking at the new users log, at 14:34 pm (UTC+8), 15 Jan 2006, going back 20,000 entries gets you

Some analysis:
 * That means 20,000 accounts were created in five days.
 * That's 120,000 per month, given a 30 day month
 * This is verified if you do offset 120,000 into the list:

20,000

2.78 accounts per minute, which is about what Less then three days ago

Solutions
No easy solutions to this phenomena. Here are some suggestions:

Account aging
Delete all accounts older than "n" days and have no edits. Ideal number for "n" is perhaps 2 days. It's not obvious whether there is a legitimate reason to have accounts created, but not used, for so long.
 * Pros - Does not burden legit registrants
 * Cons - escalates the battle. Vandal may write script to make small dummy edits right after creation, just to not be an empty account

CAPTCHA or some type of Turing test

 * Pros -
 * Cons - one more step in registration, historic resistance to this "anti-wiki" concept

E-mail activiation code to user

 * Pros -
 * Cons - one more step in registration, requires e-mail address

Account creation throttling

 * Pros - Does not require additional registration info
 * Cons - may be legitimate reasons (ie. school exercise, high profile event)
