My spammer problem is so bad this week that I sat down and figured out how to do this. Here’s the mini plugin I wrote. It restores the “Mark as Spammer” link in the admin bar and adds a “Spammer” button to the activity stream: https://gist.github.com/3815688
YES PLEASE. I’ve just marked about thirty spammers, and I’m not done yet. It takes longer now that the link in the admin bar doesn’t immediately mark people as spammers, but takes me to the profile where I have to traverse the whole page to reach the checkbox and then submit the form.
