dannydarko,

I know of no "tags" that have become illegal in the past few years, or ever. If the "tags" (file descriptions?) you mention include references to child porn, well, they haven't changed, either.

I suggest you read and follow the suggestions from UKBobby and Orange County, above your post. Then you should stay away from p2p. And you can tell the RIAA/MPA that you've done your job.
