A blogger I follow is being harassed on her site. She’s done a key thing: blocking the email addresses from setting up new accounts and providing more abusive comments. One thing that people can do in addition: set comments for manual approval. Though it doesn’t prevent someone from sending you abusive comments, it does prevent them from being seen on YOUR site. It’s a simple process to set up.
First, head to your dashboard. Scroll down the left-hand side until you see “settings”. Click on that, the look for the link to “Discussion” (the image directly below is from the WordPress.com dashboard, linked via JetPack. If you’re in your site’s dashboard, you’ll see “Discussion” open up below…that’s the third image below). The last part is simply checking “Comment must be manually approved” then clicking “Save Settings”. Now, any time someone posts a comment, you’ll get a message asking if you want to approve it. It provides some sense of security via control.
Here’s where to find it on your self-hosted WordPress Dashboard.
