Polygram Records – Villian or Saint?

So when I did my RIAA member list purge of the CDs on my wishlist, I left all the Polygram Records albums, because Polygram is not listed on the list. I admit to being surprised by this, but pleased nonetheless. However, the RIAA radar, an excellent searchable database, has Polygram listed as offenders. I’m not sure why, the list they link to (and presumably used to generate the database) doesn’t have them on it. Polygram was recently bought by Seagram, another label not listed in the set of evildoers. So, what’s a person to do? If anyone has any information to give me on whether Polygram is or is not an RIAA member label, I would appreciate it. Thanks!
