Unfortunately, without KAT, I simply refuse to upload any content. KAT's categorized sections were what inspired me to start sharing rare music that is unavailable anywhere. TPB is a disaster area (pop-up ads keep infesting my browser every time I click on a link and before anyone whines, my machine is not infected with adware or malware) and there isn't an alternative that I have found that comes anywhere close to KAT. It had been ten years since I uploaded anything and when I decided to upload something, KAT gets seized. I just don't have any confidence in the alternative torrent sites to even go back to uploading. What strikes me is that KAT still hasn't resurfaced. As many times as TPB has resurfaced, KAT should have resurfaced by now but it is unlikely that I'll go back to uploading without the return of KAT.
What's sad about it is that I have 400GB of music that I was willing to share with KAT users. I'm just going back to what I refer to as 'download and stop'. There isn't a single torrent download site who has a similar categorized search for their site and the user interface was easy to navigate. There are only two sites I use now, ruTracker and nyaa.
