In another sweeping change to his social platform, Elon Musk has announced that hashtags will no longer be allowed in advertisements on X (formerly Twitter)—and the move has triggered a wave of online debate.
The hashtag ban goes live immediately, with Musk calling it an end to an “aesthetic nightmare” that’s plagued the platform’s ad experience. The decision, made without prior warning or advertiser consultation, aligns with Musk’s broader mission to transform X into what he calls the “everything app”—a polished, streamlined alternative to legacy social networks.
The billionaire entrepreneur didn’t mince words. In a post on X, he described hashtags in ads as “ugly” and disruptive to visual design. The goal, according to Musk, is to reduce clutter and improve how promoted posts look on the platform. “No hashtags in ads starting tomorrow,” he wrote bluntly.
This isn’t the first time Musk has meddled with long-standing internet staples. Under his leadership, X has already removed the headline preview from shared links and introduced swipe navigation in a minimalist design overhaul. Now, hashtags—a foundational element of online discourse—are the latest casualty of Musk’s pursuit of aesthetic simplicity.
The update has left many advertisers scrambling. Hashtags have long been used to boost visibility, tie into trends, and align with broader campaigns. Removing them cuts off a familiar engagement tool, especially during high-stakes events like elections, product launches, or sporting spectacles.
Ad agencies are also concerned about the lack of guidance. There's no formal documentation or interface update—just a late-night post from Musk and immediate enforcement. Marketers are now wondering what other elements might vanish next from their toolkit.
Online response has been predictably polarized. Supporters of the move argue that hashtags in ads have long been misused, often looking spammy or forcing irrelevant trends. Critics, however, say the ban could reduce ad transparency and hamper discoverability—especially for smaller businesses trying to organically join conversations.
Some users on X pointed out the irony of Musk attacking a core symbol of internet culture, especially considering his past use of hashtags for Tesla and SpaceX promotions. Others see the move as another step in distancing X from its roots as a social conversation platform and toward a curated, broadcast-first model.
This decision is more than a design tweak. It signals Musk’s continued shift toward tighter control over user and advertiser behavior on X. It also highlights his willingness to defy digital norms in favor of his own principles—even at the risk of alienating part of the platform’s advertiser base.
As X battles to regain advertiser confidence amid ongoing rebranding efforts and content moderation challenges, decisions like these will continue to define whether the platform evolves—or unravels.
For now, one thing is clear: if you’re planning a campaign on X, leave the # at the door.
