A Crash Course in Wikipedia Vandalism

Reader Johnny Cat wrote in to ask about which Wikipedia entries have the highest incidences of false information in them. "I'm aware that almost everything there, from Applebee's to Zorro, has errors every day," he wrote, "but something in my gut tells me there are certain topics that just attract bad submitters."

Johnny Cat—and you—will probably be as surprised as I was scrolling down Wikipedia's List of Most Vandalized Pages, because there doesn't seem to be any method to the madness of wiki vandalism as far subject matter is concerned. Among the victims of "exceptionally high vandalism" are the entries for Jack London, baseball, Halo 2, Harry Potter, piano, home improvement and buttocks. The commonality among some of the most vandalized entries seems to be that they're recent major news events, topics that are currently, or have been, subjects of controversy, or entries that are simply popular and often read.

Back up. What is wiki vandalism in the first place?

Wikipedia defines it as any "addition, removal, or change of content made in a deliberate attempt to compromise the integrity of Wikipedia," which can come in variety of flavors, such as...

Blanking: Removing all or significant parts of a page's content without any reason, or replacing entire pages with nonsense.
Page creation: Creating new pages with the intent of malicious behavior, like blatant advertising pages, personal attack pages and hoaxes.
Page lengthening: Adding large amounts of bad-faith content in order to make the page's load time abnormally long or even make it impossible to load without browser crashing.
Spam: Adding external links to non-notable or irrelevant sites or sites that have some relationship to the subject matter, but advertise or promote in the user's interest.
Silly vandalism: Adding profanity, graffiti, random characters or other nonsense to entries or creating nonsensical and non-encyclopedic pages.
Image vandalism: Uploading shock images, inappropriately placing explicit images on pages, or using images in other disruptive ways.

Once the damage is done, how long does it take to fix?

In the interest of science, Wikipedia user Colonel Chaos vandalized featured articles, the entries that are considered the cream of the Wikipedia crop. Since Wikipedia employs software created to help find easy-to-spot vandalism (like "Your mom!" or "POOP!!!!"), the Colonel engaged in slightly more complex vandalism of three types: Complete Nonsense, where passages of completely irrelevant prose were inserted into articles; Grave Factual Accuracy, where material was changed or inserted in a way that it would be obvious to the average reader or editor of Wikipedia that the material was untrue (e.g. That Martin Sheen discovered hydrochloric acid by mixing potatoes with salt and invented Agent Orange for the purpose of dissolving gold); and Factual Inaccuracy, where articles were changed slightly so a reader would need some knowledge of the topic in order to spot the inaccuracy (e.g. the article on Norman Borlaug was changed from "Between 1965 and 1970, wheat yields nearly doubled in Pakistan and India" to "Between 1968 and 1975, wheat yields nearly tripled in Pakistan and India."

The average response time on these changes were 11.5 hours for Complete Nonsense, 9.25 hours for Grave Inaccuracy and 57.4 minutes for Factual Inaccuracy. Colonel Chaos notes that for featured articles, which rotate on Wikipedia's main page and are heavily viewed, a reversion time of 10 minutes would be more appropriate.

Here are some highlights from the study:

Article Elapsed Time between vandalism and reversion
Medal of Honor 1 Minute
Hydrochloric Acid 14 hours 16 minutes (Edited by an automated bot in between Colonel Chaos' edit and the revert).
Second Crusade 42 hours 38 minutes (According to Colonel Chaos, "This one suffered another incident of vandalism and was reverted to my version before my modifications were corrected. Honestly, how long does it take to figure out that Gregory Peck, Bill Cosby, and Harry Potter didn't lead the Second Crusade and that Paul Revere wasn't involved?)

Is there any way to stop this madness?

Well, there was the plan to simply let vandals run amok on the entry for chickens. By sacrificing this article—"Dudes already know about chickens. Ladies also already know about chickens. Does an encyclopedia really need an article about nature's tastiest birds?"—it was hoped that the rest of Wikipedia would be spared. The plan, like the bird, never really got off the ground.

Then there's WikiScanner, created by Daniel Erenrich and Virgil Griffith, which allows users to trace the source of anonymous edits to Wikipedia entries and by using IP address of the anonymous user (which Wikipedia logs) to identify the owner of the computer network from which the edits were made. In the past, the tool has exposed insiders at Diebold Election Systems, Exxon and the CIA covertly deleting or changing information that was unflattering to their organizations. If you can't stop a vandal, you can at least pull back the curtain of anonymity.

The Real Bay of Pigs: Big Major Cay in the Bahamas

When most people visit the Bahamas, they’re thinking about a vacation filled with sun, sand, and swimming—not swine. But you can get all four of those things if you visit Big Major Cay.

Big Major Cay, also now known as “Pig Island” for obvious reasons, is part of the Exuma Cays in the Bahamas. Exuma includes private islands owned by Johnny Depp, Tyler Perry, Faith Hill and Tim McGraw, and David Copperfield. Despite all of the local star power, the real attraction seems to be the family of feral pigs that has established Big Major Cay as their own. It’s hard to say how many are there—some reports say it’s a family of eight, while others say the numbers are up to 40. However big the band of roaming pigs is, none of them are shy: Their chief means of survival seems to be to swim right up to boats and beg for food, which the charmed tourists are happy to provide (although there are guidelines about the best way of feeding the pigs).

No one knows exactly how the pigs got there, but there are plenty of theories. Among them: 1) A nearby resort purposely released them more than a decade ago, hoping to attract tourists. 2) Sailors dropped them off on the island, intending to dine on pork once they were able to dock for a longer of period of time. For one reason or another, the sailors never returned. 3) They’re descendants of domesticated pigs from a nearby island. When residents complained about the original domesticated pigs, their owners solved the problem by dropping them off at Big Major Cay, which was uninhabited. 4) The pigs survived a shipwreck. The ship’s passengers did not.

The purposeful tourist trap theory is probably the least likely—VICE reports that the James Bond movie Thunderball was shot on a neighboring island in the 1960s, and the swimming swine were there then.

Though multiple articles reference how “adorable” the pigs are, don’t be fooled. One captain warns, “They’ll eat anything and everything—including fingers.”

Here they are in action in a video from National Geographic:

The House From The Money Pit Is For Sale

Looking for star-studded new digs? For a cool $5.9 million, reports, you can own the Long Island country home featured in the 1986 comedy The Money Pit—no renovations required.

For the uninitiated, the film features Tom Hanks and Shelley Long as hapless first-time homeowners who purchase a rundown mansion for cheap. The savings they score end up being paltry compared to the debt they incur while trying to fix up the house.

The Money Pit featured exterior shots of "Northway," an eight-bedroom estate located in the village of Lattingtown in Nassau County, New York. Luckily for potential buyers, its insides are far nicer than the fictional ones portrayed in the movie, thanks in part to extensive renovations performed by the property’s current owners.

Amenities include a giant master suite with a French-style dressing room, eight fireplaces, a "wine wall," and a heated outdoor saltwater pool. Check out some photos below, or view the entire listing here.
