today i found a lot of these entries in my logs:
208.82.16.128 - - [04/Jan/2011:09:13:35 -0500] "GET .......... HTTP/1.1" 200 580138 "............" "FeedBurner/1.0 (http://www.FeedBurner.com)
The IP belongs to the Ning network. Do they have anything to do with Google or Feedburner? If not...this is serious foul play from their part!
