I'm not a robot, honest

[caralampio]

Just to voice an opinion, the captcha thing to prove that you're not a robot is getting quite annoying. I mean having to take an intelligence test every time I want to come in, sometimes two or three test panels (which squares have wheels, which squares have cars, etc.) it's a real bother. I come into nexus several times a day, couldn't there be a cookie or something so you only have to prove you aren't Mr. Roboto once a week or so. Or make simpler, I'm fed up with the IQ tests.

I have yet to come across this situation. Maybe offer the devs more details?

do you sign out daily or something?

If you're running NoScript or a similar script utility, disable it for this and any other trusted sites. You'll get a lot more verification prompts if you don't.

This prompt is being done via CloudFlare who provide certain levels of security for the site. If they are showing you a Captcha, it's likely because you're on a network or IP range which has been known to do nefarious things recently. Potentially, it could mean you or someone on your IP range has been a part of a botnet and DDoSing a CloudFlare service recently, or something of a similar ilk.
