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 through flows, which will check a user’s action and validate the conditions for that action. The flow will then be able to trigger reactions for some of Decidim’s most critical resources.

• The user's profiles
• The user's personal URL
• The writing of comments
• The creating or updating a meeting
• The creating or updating a proposal
• Ability to login and register

With this anti-spam module, the flows will always perform like this:

• Check the user action
• Validates the conditions you have configured
• If your condition classify the action as spam, then executes the actions you have configured

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