At least it is technically possible to complete the dreamwidth captchas now. For many years (well before the modern corporate spidering insanity) dreamwidth was just completely inaccessible no matter how many times one completed their captchas. You'd have to be running a recent version of Chrome or the like.

Now after doing the captcha ~5 times and getting nothing a different captcha pops up that actually works and lets one in.

It's not good but it's a hell of a lot better than their old system.
