How to import someone's friends from their comments with Spyder.
Select a user in the main window.
Click the Download Users that Posted Comments button:
You can also choose Action > Import Users from Comments…
The search comments window will display.
Choose options for performing the search.
Click the Import button to perform the search.
When the search completes the results will appear as a new folder on the sidebar.
If you have the Only Strangers checkbox enabled don't be alarmed if the search doesn't have any new results. It just means no new comments have been posted to that person's profile.
