EDIT:
Also, one more thing I tested and keep getting an error on. In Scrape lists I tried creating a custom search: Latest track of > Users who commented on track and select the Result type as "Profiles." I then paste in the URL for the artists page and hit search. This is what happens when I do that:
Processing search: custom_search
* ERROR: Object reference not set to an instance of an object.
* UNKNOWN ERROR OCCURRED - see logs for more info.
If the problem continues, please submit logs to support.
