I found how MCA fails Participation. It seems pretty mild, though: 5: A>B>C 4: B>C>A
A is a majority favorite and wins. But add these in: 2: C>A>B There is no majority favorite and B wins by greatest approval. The two voters would have done better to not cast these votes. Or, if they had polling info, they should've voted CA>>B. Best not to waste the first rank on an unviable candidate. The reason I don't think this is a severe violation is that it should only happen when your vote prevents someone from winning with a majority, giving victory to someone you like less.
