farm4.static.flickr.com— Obscure user, 400 odd diggs in less than an hour all from newly created accounts... someone figured out how to play with Digg's captcha.

Am I the only person who has not seen a Captcha on Digg in well over a year now? Is this something that comes from being a member for a certain amount of time, or is it based on some algorithm for authenticity or what? I've always wondered this when people bitch about the Captchas.
The easiest way to prevent that, and one that I can't imagine not being present on digg, is simply clear the session variable storing the correct value (or hash of the correct value) for the CAPTCHA after you successfully match it. Nothing has to be stored on the server side, and the user can't perform the trick you just described.
Thankfully, no they were talking about justjeninsf, above, with +159Hey Jen, what do you have to say about the trolls that obviously, predictably, and viciously bury anything 'Liberty oriented' and gloat about it, without ever explaining themselves except to hurl insults? The ability of a handful of humbugs to actively suppress an entire community on digg is a serious slap-in-the-face to the democratic nature of digg.. should admitted bury-addicts really have as much weight as they do?
Jpeg can handle text just fine. It all depends on the compression ratio of the program you're using. By default most set the compression low because of the exported file's size. I agree with you completely about using png wherever possible though. It has a much better compression/quality ratio in most cases.
Only had to solve one when registering and for my first comment. It received a few diggs, and apparently that convinced the digg server monkey I was (at least partially), human.

I think ebay's programmers can come up with something that will work. Just look at their 'best match' search algorithm.

Good one Anton. If you think Anton deserves a raise Digg this.

@neurobox, I've submitted recently, and have not seen a captcha in at least a year.

When in doubt of which format to use stick with PNG. I find it has the best overall quality/size for many types of images, particularly screenshots.
