X (formerly known as Twitter) has started rolling out a new ad product that cannot be blocked or reported. Users reported the new ad format to Mashable, claiming these posts cannot be liked or shared. This new ad type could also be an indication that X is experiencing a shortage of advertisers investing in targeted advertising. The new ad format looks like a regular post, consisting of text and a photo. People who have clicked on the new ad format have reported being taken to third-party websites in a new window.
