Ahref's Disavow Data Made Public
Maxwell Pond
Explanation: 
Ahrefs asks if users want to upload a disavow file when doing keyword tracking. 
What if you made that data public in a database that allowed us to see how many people have domain example.com on their disavow list? 
EXAMPLE: I search for example.com in this database
Ahrefs says- 1,045 have example.com on their uploaded disavow. This is in the 20th percentile of most disavowed sites.  (or something similar to this?)
