Wu Shuo learned that according to the latest "Paid Partnership Policy" released by X, cryptocurrencies (Crypto) have been listed as a prohibited industry for promotion. The policy states that content involving financial products, services, or opportunities, including loans, investment services, cryptocurrencies, and "buy now, pay later" services, are not eligible for paid partnership promotion. X emphasizes that all paid partnership tweets must include clear labels such as "Ad" or "Promoted Content" and comply with local laws (such as FTC guidelines). Violators may face penalties such as tweet removal, account read-only mode, or even bans. Additionally, while this category is prohibited in creator paid collaborations, it may still be allowed in X Ads (official advertising spaces), subject to their specific advertising policies.
