>Thanks for the report! This was an overactive anti-abuse system. Fixed.

This is the most interesting line to me. "Anti-abuse system"? I would bet the system is far from being just a conditional on a specific filename. In other words, this supposed anti-abuse system might be far more pervasive without the user's knowledge. And perhaps even more importantly, who thought upcharging instead of blocking is the correct approach to dealing with this alleged "abuse"? Is this some anti-distillation feature they let Claude itself write looking at past distillation attempts producing similar artifacts or what?
