General

What does "high-availability" mean?

The Mollom infrastructure was built from the ground up to be scalable and robust. Mollom has servers in multiple independent data centers around the world, providing a high degree of redundancy.

Mollom also uses a load balancing mechanism: when one of the Mollom servers is down or overloaded, your site can move on to the next Mollom server. This mechanism allows for high availability, as it is unlikely that different servers in different data centers around the globe would simultaneously be unavailable. Mollom servers are permanently monitored, and Mollom has technicians on call that can respond to any emergency 24/7 should any issue arise.

Mollom provides paying customers a Standard Service Level Agreement that sets forth the service delivery criteria that Mollom endeavors to achieve with respect to the Mollom servers. Mollom users with a free Mollom subscription do not receive any service level agreements.

Aren’t CAPTCHAs an accessibility problem?

Web site accessibility is a very big issue. Adding image CAPTCHAs to web sites makes them inaccessible to visually impaired people using screen readers or braille screens.

Mollom allows users to request (English only) audio CAPTCHAs, which can be solved by visually impaired users.

But more importantly, only a very small percentage of users will ever see (or hear) a CAPTCHA! Using intelligent filtering techniques, we present CAPTCHAs only to users posting suspicious content. By using Mollom, your website becomes both more accessible and better-protected.

What is a CAPTCHA, anyway?

CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." It is a type of challenge-response test used to determine whether a user is human. This is done by asking a user to solve a challenge that is hard for computers, but relatively easy for human beings. Mollom currently supports both image and audio CAPTCHAs.
