From the Administration Panel, I wish there was some sort of “Watching Settings”, where you can:

• Block an individual from watching your site
• Temporarily turn off watching for Wiki pages (let's say you're making a surprise)
  • Per Category
  • Per Site

Blocking certain individuals from watching my site is especially important to me. I have a certain undesirable who I have banned and blocked from contributing to my site and forum.

This person, however, is still watching my site, and still receiving emails whenever I make a page change or a forum post (kind of creepy).
