forward spam to spam folder

Spam is marked as spam but not moved to the spam folder.
Is it possible to make a filter that automatically moves these mails to the spam folder? Or is there an option for this?

As a kind of follow-up, is there a mechanism where users can report spam that bypasses the filter? I don’t mind moving spam I receive into my local spam/junk folders, but I’d like to contribute this determination if possible so others might not get the same spam I do.
