Since July 2025, the CR4 site has implemented an OTS, AI-backed spam solution from a third-party vendor. This deployment allowed CR4 admins to re-open public registration after a few years of closure.
This filter has been highly successful in stopping bot and human-created spam drivel.
However, some users have reported false positives from this filter, which prevents legitimate posts or comments from being published.
We sincerely apologize for this inconvenience. We are seeking solutions and ask for your continued patience. If you experience this, we invite you to try your post again at a later time.
We'll issue updates in a future announcement. Thank you.
