Private Tracker. Just do the MAX trial and download 720p using streamfab.

Seems like they are using CGNAT, which means you won't be able to connect to some peers who are also not connectable due to both closed ports. One must open their port to establish connections.

They can surely remove you from CGNAT but for extra cost. I think paying for seedbox is much cheaper.

Do they do it just to feel superior about bring in a sekrit club?>

Yes.

Tho it takes time to join or never to their sekrit club. They look down on people who pick low quality or uses real debrid or DDLs. They will also ban you once they confirmed you are uploading to DDL sites.
