Its usually through a part of the forums they have, you might need to reach specific requirements to see them. I got into most trackers im on through open signups. Others allow you to do an interview and if you pass that you get invited.
If you cant access the invite forums then making requests is your best bet, they are usually filled quickly and keeps you from having to watch your ratio on multiple sites.
If also just checked and have a few TL invites. If you want one shoot me a dm
Private trackers will probably be your best bet imo if you want to stick with torrents, any popular genarl private tracker will probably be enough. If they dont have it already you can request it and someone will probably have it uploaded in a few days (unless its something really obscure). If you can seed long term and maintain a good ratio then getting into more specilized tracker wont be a issue. If you want I can check if I still have an invite for Torrentleech, they might have what you are looking for.
False positive, most of the detections list them es generic or vmprotect. If you still dont trust it you can make your own fix, there are tools for that on rin.
Dead torrents are a lot less common as people are often rewarded for seeding torrents for long periods of time or seeding torrents with very few seeds. You often get faster download speeds on torrents with few seeds as people often use seedboxes to maintain ratio.
Dont think that true anymore, im no expert but rips from tidal or quboz sound way better to me then cd rips did
If used them a few times before tools to rip from streaming services became as common as they are now and thkse releases are fine. Dont really see a reason to use them nowadays tho besdies the scenes seal of approval.
Also I get your frustration with people not understanding what you mean with "scene" here, but tbf you could have specified which scene, in this case it would be the warezscene that you are talking about.
For those unaware about the warezscene, they are the groups that make releases for every type of media and are bound by rules (you can look them up if you wanna know specifics about those), the names the op mentioned are a result of those rules.
Just dns blocks, s.to for example has a site dedicated to lising all domains of theirs and ways to change your dns server which isnt blocked afaik. serien.domains if you wanna check it out
Scene groups only release to other scene groups via ftp servers, they dont release in places the average joe can download them. Their releases trickel down from people with access to those ftp servers and hit usenet and private trackers before then hitting public trackers.
CODEX (and any other scene group for that matter) has no website, they dont release to the public.
You can always check the megathread here or fmhy.net for sites that might have it. cs.rin.ru seems to have downloads for X-Plane 11 and 12 from a quick search.
Ultra.cc has 1tb seedboxes for 5€ a month but iirc you cant pay with paysafe cards
fmhy.net has some tools listed in their audio ripping section that might work, haven't tested them myself.
