I dont know what is causing but i tried tons of fixes, i mainly use public torrenting, and sonarr and radarr are doing it.
I added *.arj and arj to the quality profile avoid list without success, and prowlarr is as torrent (i’ve read sometimes it gets confused and uses nzbget)
The sonarr devs keep refusing to do this because “use better trackers”.
They don’t understand most people can’t join the top of the line trackers right away, and that using public trackers is a massive help to filling the gaps, even if they unfortunately get crappy files from time to time.
I went down the rabbit hole on this the other day as I was trying to find a way to block unreleased episodes. It’s unbelievable to me the resistance they put against such a simple feature. Like no one is requesting to force it that way, just give the option to make it so.
The two reasons I saw for canceling the feature request over menu duplicates is the “use better trackers” mainly but also that shows are so often released or leak early they this setting would block you from getting them faster… Those are the dumbest reasons ever to not provide a setting that people are literally asking over and over again for.
The change is done for radarr so it might not be terribly hard to adapt into sonarr. Being open source I would have expected someone to do the change already but if they fight against it so much as a principle who would expect them to approve the change…
I mean, I’ve only gotten those from one tracker, and haven’t gotten them since I’ve removed that one tracker. Sonarr at least recognizes it’s not a media file and won’t copy it to your media folder. And you can use regex filters with qBittorrent. There hasn’t been a legitimate use of .arj in what, 30 years? So you won’t be missing anything by filtering it.
