Can I report phone numbers as spam callers? Google recently introduced a feature that lets me know if someone is a suspected spam caller. However, sometimes I get calls from numbers that aren't listed as spam callers but are still spam callers. Is there some way I can report these?

Yes, you can report callers as spam. 

From Google support:


  You can mark all calls from a number as spam to keep from getting any more and to report the spammer.
  
  
  Open your device's Phone app phone.
  Go to Recent calls Recents.
  Tap the call you want to report as spam.
  Tap Block / report spam. You’ll be asked if you want to block the number.
  If you have the option, tap Report call as spam.
  Tap Block.
