According to a report from TechCrunch, Twitter/X has started displaying non-labeled advertisements in a subtle manner, resembling normal text posts that don’t explicitly identify themselves as ads. TechCrunch conducted experiments and confirmed the existence of these inconspicuous ad posts, by noticing the removal of the word “Ad” at the top right corner. These covert advertisements lack the time stamp usually found in regular posts and can be identified by clicking on the … button in the top right corner. If the menu resembles that of an ad, such as “Why this ad?”, then it can be concluded that it is indeed an advertisement.
TLDR: Twitter/X is now showing unmarked ads disguised as regular text posts. TechCrunch verified this by discovering ad posts without the word “Ad” and without a time stamp. Users can confirm if a post is an ad by checking for an ad-specific menu option like “Why this ad?”.
