As I said many times, except for the sudden huge promotion and gifts thingy which was proven by avex itself, there is no other proofs for anything else they did. No proof, not a fact. (And again, using the abnormal high rise in sales is not a proof).
Everyone can think that there was an "avex mocus" but still, there is no proof for that.
Usually the people that want to think that don't like ayu as well so it's not surprising.
