[Jane Street Official Fraud Alert: Does Not Provide Services to Individual Investors, Does Not Solicit Business Through Social Media Platforms] According to a fraud and impersonation warning disclosed on Jane Street's official website on February 26, the company does not provide any services to individual investors, does not offer any mobile trading applications, online accounts, or any other personal services, and does not solicit business through WhatsApp, Telegram, Signal, LINE, Viber, or any other instant messaging or social media platforms. Jane Street does not offer direct investments in cryptocurrencies, pre-market trading, stocks, or any other investment services and has no affiliation with companies or groups such as Finology AMC, DeepQuant, or any other similarly named entities. Previously, there were rumors in the community that Jane Street's official X account had deleted all tweets. However, some individuals in trading circles pointed out that the account historically had no posting activity (as evidenced by Wayback Machine archives showing it was empty for a long time). The current '0 tweets' status may not be due to sudden deletions but rather a long-standing state, which has been amplified into conspiracy theories by litigation-related news.
