X has introduced new regulations requiring all paid promotional content to be clearly labeled as "Paid Promotion" or with similar tags. Failure to comply will result in penalties ranging from content removal and account restrictions to suspension or permanent bans for repeated violations. An appeal process is available for affected users. While cryptocurrency promotions are not globally banned, they are restricted in Australia, the EU, and the UK due to local financial regulations. In other regions, promotions are allowed but must be clearly disclosed to avoid being classified as undisclosed advertising.
