The problem with torrents are that usually you have to download all pack and then choose what's useful for you and what's not. I will gladly download 5-6 HDRI's when links became more alive, but to have whole 150 on HDD, why on earth somebody needs it?
Edit: BTW, i blame those HDRI's for very slow forum attachement loading lately. Sometimes i have to wait few seconds to load single image in gallery. Hopefully everyone will download HDRI's they need in a few weeks and things became normal again.
