KrebsOnSecurity reports on a scheme where sanctioned Russian banks are using cryptocurrency to access the international financial system. These banks partner with over-the-counter (OTC) cryptocurrency desks, which facilitate large transactions outside of traditional exchanges. Russian businesses deposit rubles into the sanctioned banks, which are then used to purchase cryptocurrency from the OTC desks. These desks, often operating in countries with lax regulations, then sell the cryptocurrency on international exchanges for foreign currencies like dollars and euros.

The Hacker News post titled "Show HN: I built an active community of trans people online" linking to t4t.social generated a substantial discussion with a mix of perspectives. Many commenters expressed strong support for the creation of a dedicated space for trans individuals, emphasizing the importance of community and safe online interaction given the prevalence of transphobia elsewhere on the internet. Several commenters praised the site's design and functionality, particularly its clean aesthetic and intuitive user interface. Some specifically highlighted the value of features like content warnings and the focus on fostering positive interactions.
A recurring theme in the positive comments was relief and appreciation for a platform designed to circumvent the harassment and discrimination that trans people often face on mainstream social media sites. The sentiment was that t4t.social offered a haven where trans individuals could connect with one another, share experiences, and build relationships without the fear of being targeted or marginalized.
However, the discussion also included critical viewpoints. Some commenters raised concerns about the potential for echo chambers and the limitations of self-segregation. They argued that while creating safe spaces is important, separating communities could hinder broader societal understanding and acceptance. There were also questions about scalability and the challenges of moderating content to maintain a positive environment while respecting free speech. One commenter suggested the platform might benefit from clearer guidelines regarding acceptable behavior and content.
Another point of discussion centered on the technical aspects of the site. Commenters inquired about the platform's infrastructure, the choice of technology used, and the long-term sustainability of the project. There was interest in whether the platform was open-source and the possibility of contributing to its development. A few users shared their own experiences with building similar online communities and offered advice based on their learnings.
Finally, some comments offered constructive feedback and suggestions for improvement. These included ideas for additional features, like improved search functionality and more granular control over privacy settings. There was also discussion around the importance of accessibility and ensuring the platform is inclusive for trans people with disabilities.
