People use the term friends very lightly these days.
In my opinion its a matter of perspective, I mean, is someone really a friend just because he's on your friendlist?
Or is it just someone you know vaguely or have something in common with.
I generally am pretty picky whom I add on my T11 friendlist for example, mostly are collegaes or real-live friends. Also a few managers who share the same ideology(powertraining, thinking out of the box with formations, stuff like that)
I only support all , if i happen to be logged in and their match is playing.
Other than that I don't vote against players in my league, I believe that is only a set up for back-fire.....imagine pissing a few competitors off and have them all NOT support you, on a regular bases.......Some might even take it personal and aim to make it their mission to try ruin your efforts as much as they can, preferably with the help of their buddies lol.
At the end of the day though, this is a game, when I play, I like to play to win. At least do my very best to do so. Without cheating or other ignorant methods offcourse. So I dont cut deals, dont go easy on who ever, as I dont expect others to do same.
May the best win
