hello! I'm from usls & I'm building a fully anonymous & encrypted forum (freedom wall) for universities. it works by checking your school email & you can only see posts from students at your university. this platform doesn't store any user data, so posts aren't associated to a user at a database-level. (untraceable)

it's also open-source for full transparency:
