Because in its "select all pictures containing a car" it had a picture of a woman getting locked in a car trunk and I'm not sure I'm OK with a captcha whose image base appears to include crimes in progress.

(I admit, it's probably the VPN setting it off in the first place, but some of these images are kinda... odd.)

EDIT: So I got the laptop off the corporate network and off VPN and the captchas went away. Must be that, and it must be new since it wasn't doing that yesterday under the same conditions. Anyway, thanks for the thoughts on the issue, it's most appreciated!

(Still, where the hell do they get their images from?)
