I think it's because Silvermist was already Fairy Godmother status.

Note that Silvermist has a wand (silver version of Blue's). I think you can break rules on like a strike system. Three strikes and Blue comes and takes your wings away.

Tink had lost her second and third chance, so she was dropped from fairyhood.

Silvermist is like an ambassador in Wonderland. Blue is likely her boss, but since she's a great deal away, she gets away with more things than others.

My theory, at least.
