The way I see it, Captchas are an approach to fend off _untargeted_ spam bots. If someone specifically targets your website and tailors his spam bot accordingly, then you have a problem, but that is not inherent to Slider Captchas.
On the other hand, a Slider is much more user friendly than a scrambled image or having to select all pictures with light bulbs.
So I think this article misses the point a bit...

- TazeTSchnitzel 7y agoI am one of the admins on a forum for an open-source video game. We have two extremely easy questions required on signup (one asks for part of the domain name of the site, the other is a trivially googleable game fact) purely to stop untargeted spam attacks and it is remarkably effective. Of course some spammers get through, but that's why we have moderators.
