| You've noticed [[spam]] on the internet [[Kimmo Alm|flooding from bots]] at some point or another, right? It's estimated that 99.9999% of all email is spam. How did it get this way? It's thanks to a little thing called the '''CAPTCHA'''.
| |
|
| |
|
| In the old days, websites had intelligent limits based on IP addresses and heuristics and all that. Now, they just use CAPTCHAs. For what reason? [[GodJesus]] only knows because they're not stopping the spambots. FACT: No human has ever gotten past a CAPTCHA, ever, not once. Eventually the human just gives up, goes to [[The Pirate Bay]], downloads XRumer, and has that program solve the CAPTCHA for them.

| ===ReCAPTCHA (and how to fuck it up)===
| |
| [http://www.lifelan.com/blog/how-to-mess-with-recaptcha/ reCAPTCHA] holds the potential for unmitigated lulz. [[Last Thursday]], some geek decided it would be a [[Gay|fabulous]] idea to turn CAPTCHA into a method of obtaining nigger labor. Here's how it works; lots of people and companies want to scan books, but computers aren't very good at reading text, especially old shitty, blurry, text. [[Google|They]] could hire people to read the words the computer can't, but are far too busy guarding their [[Jew gold | joo golds]]. Instead, they've decided that relying on the drunken, mischevious, volatile hordes of internet users [[Not|is a good idea]].

| Unlike a regular CAPTCHA, reCAPTCHA's have two words, and that logo you see over there. One word is a regular CAPTCHA, the other (usually the second) is a word scanned from a book[http://recaptcha.net/learnmore.html]. You have to get the CAPTCHA right, but since the computer has no idea what the fuck that other word is, you can type anything you want there. Some helpful suggestions: fag, goatse, nigger (extra points if it's someone's name or an adjective), lolwut, longcat, goatse, etc... For all the computer knows, it really says that and it's stupid enough to take your word for it. You don't get to see the result of this yourself, but you do get the satisfaction of knowing that someone out there is reading an ebook about how Sherlock ''Goatse'' ''raeped'' Professor ''McNiggertits'' with his ''pointy porksword''. Though four people must type the same word and nigger is the common one people type for the scanned word--this is called re.
| |
|
| |
| In the original reCAPTCHA it was easy to tell which word is the scan and which is the CAPTCHA, the scan would be clear and have a line through it while the CAPTCHA would be wavy. Thanks to massive [[trolling]] to protest CAPTCHAs they've changed it a little; now both words look mostly alike but the discerning troll can still tell the difference. The scan usually has slightly blurrier edges, and is usually an old and/or weird word, a name, or verbose math terms with symbols. In the example above, the scan is the first word.
| |
|
| |
| Recently, Google has begun replacing the CAPTCHA words with bizarre letter combinations that vaguely resemble words, but aren't really words. In fact, you can almost guarantee that if you see an actual word, it's the book word, not the CAPTCHA.

| [[File:Not a bot.jpg|thumb|ReCAPTCHA claims you have to just click "not a bot now". In truth, the "not a bot" is stage one. After that you then have a popup window which is blocked by most browsers so you have to use IE. And then after that, it expires in 10 seconds so you have to be quick or are forced to do another one.]]

| ==Wikis==
| |
| [[Wikipedia]] and [[Wikia]] both use CAPTCHAs for registration to prevent vandalism. This actually works because most vandals (as opposed to [[Grawp]]) are too lazy to download a software to read the CAPTCHAs. And in fact, our very own beloved [[Encyclopedia Dramatica]] uses CAPTCHAs for just about [[fucking everything]], to maintain our [[No|lofty standards]] of [[Shit|quality]].
| |
|
| |
| ==On some sites, every single step you make requires solving a CAPTCHA==
| |
| MySpace is the typical example:
| |
| *Changing their password
| |
| *Registering a new account
| |
| *Sending comments
| |
| *Friend requests
| |
| *Logging in, even if the password is typed correctly.
| |
| *Modifying profiles
| |
| *[[What|Sending someone a message]]
| |
| *Calling 911
| |
| *Every time you click a page no matter what
| |
| ...but if you have a cell phone, you can text MySpace so you no longer have to do CAPTCHAs.
| |
|
| |
| On [[eBay]], you have to solve a CAPTCHA to send yourself a test message and sometimes even to view your own feedback profile if you're logged in. It also has CAPTCHAs all over its website, and sometimes these are broken for days, rejecting all correct answers.

| ==reCaptcha on /b/==
| |
|
| |
| Recently, [[moot]] finally got sick and tired of all the spam that had been recently "Engulfing the whole site".
| |
| The spam purportedly came from some random people in an IRC channel with a homebuilt spamming script and a huge list of proxies, posting VALVe video game characters.
| |
|
| |
| /b/tards are spamming reCaptcha with the word nigger, they call it Operation Ebook
| |
| *1. ask for an audio clip
| |
| *2. type in "nigger nigger nigger nigger nigger nigger nigger nigger nigger nigger"
| |
| *3. Bypass captcha
| |
| *4.???
| |
| *5.PROFIT!!!
| |
