Fact-checking organizations face severe scalability challenges because the volume of online misinformation far outpaces the capacity of manual review processes.
The claim addresses the practical bottleneck in fact-checking caused by high volumes of online information.

The remaining papers discuss automated fact-checking and NLP tools in general but do not contradict the premise that manual or traditional operations struggle with volume.
