Use the "Ban User" control to block spammers, offensive commenters and/or those who violate your commenting policy. This will block the user from posting future comments and give you the option to retroactively delete their comments from the past 30 days.
Adding users to your Trusted Users list will ensure that their comments are posted immediately though it won't prevent their comments from being marked as spam. This is used for trusted commenters, such as community regulars or website staff who aren't listed as moderators.
While banning users is immediate, retroactive deletions may take up to 24 hours to complete.
How to Ban/Trust Users
On the Embed (Ban User only)
Hover the mouse over the comment, click Moderate and then Block User.
Expand the comment, then click Ban User.
Community > Banned Users
If you're moderator with 'Settings' permissions, you can add a commenter's username, email address, and/or IP address directly to your forum's master Banned User or Trusted User list.
Banning/trusting email domains
Email domains like
example.com can also be banned/trusted at Settings > Access Control by selecting Domain in the Add item > Type dropdown.
Keep in mind: Banning an email domain will block anyone using that domain from posting comments to your site, whether intentional or not. For example, banning the
gmail.comdomain will block all users with an email address ending in
@gmail.com from posting comments to your site. When possible, we recommend blocking individual users before blocking domains.
Finding Banned/Trusted Items
You can search your Trusted/Banned Users lists at Disqus Admin > Community > Banned Users.
Can't find a blocked commenter?
Check your banned IP addresses
If possible, find the blocked commenter's IP address from a previous comment and search your Banned Users list for it.
Keep in mind: Banning an IP will block anyone using that IP from posting comments to your site, whether intentional or not.
Search by email or IP for guest commenters
Guest commenters can only be banned using an email address or IP address since they don't have a username.
Looking for a third-party service username?
Non-Disqus commenters have a username similar to twitter-123456789. You can find this username by expanding a user's comment in the Moderation Panel and then clicking the user drop-down.
