"Star ratings are simply one way of voicing opinions on your work"
Opinions, in real life, are expressed in first person (i hope it's the correct english phrase... sorry i'm italian) .
Anonymous opinions haven't any value, in any place in this world.
So, for what i can understand, you eventually don't want to explain or comment your rates... should be good... but i guess you would not be contrary to an automatic system that (it's only an hypothetical example) notify to me that Matrixworkz has rated my work 1 star...
