Hacker News users are debating whether to restrict new accounts from posting due to the rise of AI-generated content on the platform. A user named Oras sparked the discussion by noting an increase in clearly AI-generated posts, particularly from new accounts marked with green usernames. The issue is most noticeable in the Show HN section, where projects that once required weeks of work can now be created in hours using AI tools.

Several users proposed solutions including karma-based filtering, where posts would only be visible from accounts with minimum karma thresholds. Others suggested temporary posting restrictions for new accounts or implementing reverse CAPTCHAs that only AI could solve. Some users argued that such restrictions would only encourage bot creators to age accounts preemptively. The debate also touched on whether AI-generated Show HN projects should be banned outright, with some users noting that the quality of these projects often lacks the depth and understanding that comes from human development.

Moderators have not yet implemented any new restrictions, though users acknowledged that HN already does a good job blocking spam from new accounts. Some users suggested that the community should adapt by evaluating content on its own merits rather than focusing on the poster's account age or status. The discussion reflects broader challenges facing online communities as AI tools become increasingly capable of generating convincing content.
