The Sneak Mark (was "Slytherin" Hermione?)

Personally, I think Hermione warned everyone well enough by stating
the mission of the group and then having them sign.

Sure, Marietta was pressured by Cho, but she did sign, which gives her
some responsibility toward keeping her oath.

HOWEVER, as wrong as I think she was, it is POSSIBLE to look at her
actions as courageous.  She never trusted that Potter boy, and the
club became illegal almost immediately.  She might have decided she'd
been pressured into it, and promises made under duress shouldn't count.  

She might believe she was doing the right thing by turning them in.

In which case, though, the SNEAK mark wouldn't really be a sign of
shame for however long it took to cure, but something she was willing
to brave to do the "right" thing.  

Just as Neville stood up to the Trio in PS/SS.  Trying to do what's
right and stay out of trouble....

Oh, forget it.  She's a little rat-fink.
