When the spam team gets good tips, they will often do a deep dive to understand networks and take broad action. So reports do help.

Google has always said they read spam reports and we've seen the actions Google has taken over the years on these reports.
So while it might take time for Google to act, espesially for more broad spam challenges, Google does act eventually.
