Three buttons:
Like weight (minimum 1% slider vote)
Dislike weight (minimum 1% slider vote)
Flag - the same as it is now
'Sponsored by indicator' (Likes above 10% vote) - automatically from the 'Like votes'.
Anyway, this idea of extra things in the interface can over-complicate the experience.
Yeah I think three buttons is plenty like dislike and flag(hits reputation)
And maybe a limit on the number of downvotes you can do in a time frame.
