Decidim::SpamDetection

Usage

SpamDetection is a detection bot made by OpenSourcePolitics. It works with a spam detection service which marks the user with a spam probability score, between 0.7 and 0.99 it is probable, and above 0.99 it is very sure.

By default, the bot does not blocks the user, it only reports them. All reports and blocks are made like regular Decidim ones.

Installation

gem "decidim-spam_detection"

bundle exec rake decidim:spam_detection:mark_users

if you are using sidekiq scheduler you can use the following configuration:

:queues:
- user_report

    DetectSpamUsers:
    cron: '0 0 8 * * *' # Run at 08:00
