Not true
If I remember it correctly that small IFPI code on the plastic ring is a proof of authenticity. I don't think the bootleggers have succeeded in ducplicating that yet.

The IFPI is a standard stamp that is put on any compact disc. It only says IFPI and that's it. Every manufacture places those letters somewhere on the disc. Sometimes its laser printed into the silver area just like the ring code goes is done. It usually is in the same font as the ring code. Some manufactures pressed those letters into the plastic disc. No matter what as long as you're having Glass Master pressings being manufacture your disc will have a IFPI. This will happen despite it being a repress or not. It's a standard regulation for all manufactures when pressing Glass Master CD's. Basically all of those bootleggs that homeboy from Germany sales and any other bootlegger sales will have the letters "IFPI" somewhere on their disc. Pay attention to the disc, because they're are always flaws when it's not original. There are many things that can tell you if its the real one or a repress. You just need to see all discs that are in question/involved at the same time. You just need a good detail oriented eye.
Oh yeah... They didn't start using IFPI until the early 90's, so you will see that an album who was originally manufactured and distributed in the 80's won't have these letters on the disc. That's is if it's actually the original pressing of course.
For example: A true OG/1st pressing of LL Cool J's Radio CD (from the 80's) will not have the IFPI letters anywhere on the disc, but the repressing version will, because it was re-manufactured in the 90's. I hope you guys understand. I believe that manufactures started doing this around '92.
I suggest that you pick up about 5 random CD's from different times and you will see what I'm talking about. It's a basic/general format that manufactures use. There's really nothing special to it.
