The private tracker has always been a multi-headed beast, the mythological creature Hydra gets thrown around a bunch. While there are definately some trackers that are Best In Their Class and perhaps the most sought after, none of them are tuely irreplaceable. When a tracker goes down, the files aren't destroyed, and the vast majority of users are left alone.
While the orginazation and catalogues of years of hard work are destroyed, there is always a site waiting to step into the number one spot or A group of people waiting to rebuild. When What went down and waffles wass unavaliable as well PassTheHeadphones, Apollo/xanax, nostream, NotWhat and HydraZone all popped up ready to take their place.
Most of the reason I recently joined this comunity was my relazation that having access to a couple user class restricted invite forums was only as reliable as the site itself. For years I exclusively used three sites, because they had everything I wanted. The loss of What taught me to not put all my eggs in one basket. I've recently opened a few new accounts, and I'm now trying to find a new balance or what is easy to mantain vs insurance against shutdown.
The sad reality is that the biggest and best sites that are my favorite, are probably the highest profile targets for law enforcement as well. Once a site gets to a high profile position, eventual shutdown becomes almost inevetable. The beauty is the death makes room for the rise of new and improved sites, more innovation, and a chance for us all to build something great once again.
