R n E was a huge source for warez, they kept new files in a special area for a couple weeks before moving them and deleting warez (their way to stay legal) but they also had a location for GIFs including the ones from playboy and got busted for that.

We also had a local $50 a year members only multi line Warez BBS that a few cops were members of. Once the WWW caught on and people started to trade online via FTP sites BBS died quickly.
