On your blog, comments are activated by default. That means visitors can comment on your posts without restriction. Once you have clicked on the "Configure" section, the "Global options" tab and finally "Moderation", you can:

• Moderate the comments: only comments that you have validated will be visible by your readers,
• Deactivate comments: if you uncheck the "Activate comments" box, your visitors won’t be allowed to post comments anymore,
• Offer more options to your visitors by authorising HTML code in the comments.
• Limit the number of comments for all articles

As a blogger, you are solely responsible for the content of your blog. As a consequence, it is your duty to suppress all illicit content, such as defamatory / racist / negationist etc comments.
