Rationale - PTs drop like flies for various reasons. you better be on other trackers to fill your niche needs.
maintaining activity on many trackers can be tedious task and you better set up and forget alternatives.
RIP - GFT, BCG, TSH, TEH, WCD
if the mighty WCD fell down, we better believe the cabal is on pedestal of law enforcement agencies too and its matter of time until the holy trio will get busted.
We better join good alternatives soon rather than later.
This list should be useful reference to track which trackers are worth climbing up to, and not to get disabled after X months.

It is a WIP and any help will be APPRECIATED.

tips:
*setup and forget rpi might be a good always on seedbox.
*seed at least few torrents on each tracker just to be safe
*if you really want to lose nothing, add them to Jackett and test them every month or two. (custom script will greatly help)
