I believe this is old information and any restrictions around serving none HTML content has been removed from their terms of service related to cloud flare tunnels.
I don’t believe any of the commission methods you listed provide the same amount of compression as the tools used by some repackers.
I’m no expert. I believe UltraArc/FreeArc are what’s used to get things down so small, and as far as decompressing goes I don’t think support for those compression methods is baked in to your OS/WinRar/7zip etc.
Private trackers (e.g. TorrentLeech) often have rules around large torrents (>15gb) or even around season packs for shows. This means it’s trivial to download 4K season packs, and all you have to do is seed them for the requisite number of days (to avoid being tagged with a hit and run), rather than try to maintain a ratio.
I took a long break from pirating, but I feel like 10 years ago Denuvo meant nothing and releases were still cracked right away. Any ideas as to what changed that it all comes down to one megalomaniac?
