@Titom I'm in general agreement with what you're saying. I do think, though, that it's important to distinguish between file size and torrent size:
I don't think there's any need for a single file to be larger than 30 GB. I often transfer files to a thumb drive to watch on my large screen television, and the most common format for these drives (called FAT32) won't permit files larger than 4 GB. I have software that can break a file into sequential bits, but breaking something into ten pieces is tedious.
As for a torrent containing a large number of video files, such as a sloppy collection called "My Favourite Bareback Films" that is 100 GB, I think it's risky for a downloader to select all of the files, only to get half-way through and have the torrent deleted from the system due to a DMCA request or perhaps just one clip be suspect of having an under-18 model. It would be prudent for downloaders to select only a few of the files on offer, and then when those are complete select a few more. This can help prevent the problem of having downloaded a lot of useless partial files.
Thank you for raising this interesting topic.
