How does it work?

Behind the scenes, Decidim works with Ruby on Rails, which has a really nice way to validate things before saving them. For example:

• A user saves their profile
• Rails runs all validators
• If it's valid, it saves. If not, it shows an error

This module will add dynamic and configurable validators for some of the most critical resources of Decidim:

• The user's profiles
• The user's personal URL
• The writing of comments

With this anti-spam module, validators will always follow the same flow:

• Take the content to be saved
• Execute the rules you have configured
• If your rules classify the content as spam -> execute a spam procedure (agent)
• If your rules classify the content as suspicious -> execute a suspicious procedure

This will allow you to add as few rules as possible at the beginning of the installation and change your rules according to spammers' pressure.
