favsys.net, amazonaws.com in who's online
 

When I see many users on my "Who's online" a lot of the ip addresses resolve to favsys.net, amazonaws.com. It seems related to the fact that a post has just been relayed to my twitter account via twitterfeed.

Are these real users or some kind of bot or are people being ported through the twitter and getting their ip addresses translated?

Very interesting I think.

Many thanks!
