Recently I found myself being followed by someone I didn't know that turned out to be a spambot and was hunting everywhere for how to block & remove them. I reported and it got dealt with, I assume, by a mod. But it would save everybody time if there were a way to quickly block such "users" without the need to have them send you a sitemail or whatever -- which spammers & bots don't usually do -- before you can even see the Block User button, wherever it's hiding these days.
