What's your take on private trackers? - lemm.ee

Are they for you? Why or why not?

How do you get membership to a private tracker when they are always invite only?
Probably not a very practical answer, but I moved to a city known for being full of tech bros, then went to a bunch of general interest meetups organized mostly by tech bros, where I made friends with tech bros, and one of them randomly offered me an invite.
