Ray and skate is nothing like scallops.
> calamari and pork
Again, nothing alike.
> chocolate and flavored vegetable oil
Chocolate contains more elements than just cocoa butter, so you can't just replace it with vegetable oil. I'm sure there's some chocolate out there that cuts vegetable oil into the cocoa butter, but I've personally not come across it.
They are frequently substituted, cut out in little circles, and sold as "scallops". It is legal to do so (in the US.) The poster is complaining about mislabeling.

How is that possible? Isn't that plain lying? Can't you sue such company? As an European, I can't comprehend that. If something is labelled "scallops" it must be real scallops or else you would get sanctioned immediately after somebody finds out it's not and fills a complain. If substitutes are used, it must be labeled as "scallops flavored" or smth.
You should come to Poland. :-(
