## Pre-note

||||
|

Trackers are putting on an extremely hard job in maintaining their trackers and dealing with their trackers being taken down or hosts forcing them to shut down,
|
||||
Owners of trackers are putting on an extremely hard task in maintaining their trackers and dealing with their trackers being taken down or hosts forcing them to shut down,
|
||||
even though the service is perfectly legal. And most of the people administering trackers don't make any money, as there's no way to advertise using a tracker.
|
||||
That's why we need to show them support and help them out by creating as many small trackers as possible.
