Very rarely; if I stop talking to someone for a really long time, then I put one of my best Quibblo friends who I am currently talking to on a daily basis up there instead, but that doesn't happen often. And I feel kind of bad when I do it. :/

Whenever I get closer to someone, I'll probably move them up.
Hardly ever. I usually only do it if one of my top friends' delete their account.
I rarely do.
Whenever, really. xD
Whenever I feel like it. :)
