Ther is no way to actually affect this. You could go to dashboard -> options -> and uncheck the search engines box however, what they already have on you is out there.
You could go to dashboard -> options -> and enter zero in the show at most posts box and enter zero in the feed syndication box too. But I don’t think doing these things will actually achiveve what you’re looking for.
gotta beg dev/admins or Podz to do that if you really need.
they and only they can temporarily suspend any blog from the ‘site-admin’ dashboard.
dunno whether it’s a lame design or intentional behavior, but .com users have the only option to completely remove blog of [supposedly] their own (admittedly, I’m not sure who’s the real .com blog owner: .com user or Automattic Inc.)
