Blocking a group on Facebook prevents you from seeing its posts and interacting with its members. You can block a group if you find its content offensive, harassing, or irrelevant. Blocking a group is a simple process that can be done in a few steps.
There are several reasons why you might want to block a group on Facebook. For example, you may have been added to a group that you’re not interested in, or you may have found a group that is posting harmful or harassing content. Blocking a group can help you to avoid seeing content that you don’t want to see and can also help to protect you from online harassment.
