couple things:

• generally the rules prevent torrents from becoming incomplete
• usually theres a request system, which can be very useful for old or obscure stuff.
• usually much faster for all but the most popular stuff
• way more timely and consistent. Less problems where it takes a few days after a release for it to show up or for a series to stop being uploaded half way through a season.
• less chance of honeypots or other malicious behaviour (you should still use a VPN though obviously)
• more consistent quality and naming enforcement (which means it usually works better with *arr)

I can't vouch for this particular tracker but in general (free) private trackers are very nice.

I guess quality and sometimes s(p)eed for older/niche pieces, also no dmca bots tracking private trackers so in theory you don't need a vpn.

it's mostly to find underground stuff like festival movies, old foreign tv shows etc

I’m biased as I’m a member for 7 months. What I experienced is the admins are very active on chat and are very helpful, even users would go out of their way to help out. A lot of the users are very passionate about the tracker.

As for the donation, nothing more than a notification once in a while.

Anything over 30GB is freeleech and double upload credit, no HnR rules. Almost everything has a special freeleech.

I've been on FNP since it opened as well, haven't had any issues. It's pretty chill from my experience.

It's bonus points are very generous. Redditors always something to complain about.

General all stuff like music, applications, media, etc. I mostly use it for movies and tv series and it's really nice.

Media above 40gn is freeleech and there are lot of other freeleech content. The bonus points was also very generous and only got a bit tightened this week.
