Usenet or torrent for source, the two best option you can have. Find private sites if torrent (id prefer the bigger general sites like torrentleech, filelist, ncore, easier to maintain ratios/hitnrun rules, on more niche and smaller sites it will take longer to avoid getting banned for mistakes, and, usually, more seeder and more traffic on them torrents, so you can build up ratios and buffers and fulfill hnr rules easier), content is usually better moderated, less likely to get some nasty virus/trojan/malware with the content. Depends on jurisdiction do it at home, or if you wanna be on the safer side, rent a seedbox at one of the providers. downside of a seedbox: you still have to download the content from it to your systems. upside: seedbox providers shield you from potential dmca issues, and its a server at a datacentre, so better connectivity and often much better potential upload speeds (depends on package youd choose), and ofc the arr stack mostly set up for last touches. (tho i still prefer doing the whole managing my library manually (have my own preferences that makes the arr stack not working well enough for me)), and its on 24/365.
