Those are two different sites (.si and nyaa pantsu) due to an almost comical amount of drama between the admins of the former nyaa torrent site. Land might be a mirror of one of them but the other is an entirely different tracker.

Nyaa.si/nyaa.pant.su would be the original versions of that site, and usually have most things.

If it’s not in settings-> gestures that’s probably a phone gesture you’d need to change on your device.

Swiping right doesn’t go back for me.
