New day, new ERROR or what is that?

Was posting answers as usual for the past a few hours, then my browser freezes, in a minute I suddenly got this when tried to post another answer (I am using the same Pale Moon browser setup for the past 4 months or so):

After using backup and refreshing toms page, I got this:

Pardon Our Interruption...

As you were browsing http://www.tomshardware.com something about your browser made us think you were a bot. There are a few reasons this might happen:

You're a power user moving through this website with super-human speed.
You've disabled JavaScript in your web browser.
A third-party browser plugin, such as Ghostery or NoScript, is preventing JavaScript from running. Additional information is available in this support article.

After completing the CAPTCHA below, you will immediately regain access to http://www.tomshardware.com.

I answered CAPTCHA, and everything looks OK for now, what just happened?

We use a bot-blocking system called Distil, because we've had issues with sites scraping content and trying to phish our users, plus a lot of bots posting spam.

Unfortunately, it's a little on the paranoid side, as you've found out. Repeatedly interrupting page-loads seems to freak it out.

Reloading will generally fix it - you don't even need to fill out the CAPTCHA, usually.

Actually I was forced to do so - I refreshed open Toms tabs and got my last error screen. I have seen this first time, and at this time I was using only 1 laptop on Toms.
A few weeks ago I was using laptop and 2 PCs at the same time at Toms, and nothing similar happened.
I asked to explain my issues with using multiple PCs at the same time at Toms http://www.tomshardware.com/forum/id-2790066/strange-error.html but got no response at all.

not doing it anymore, but still interested what happened....

Multiple PCs should have absolutely zero effect on Distil - it's not integrated to our login system at all.
