I concur that torrents of collected files described only as "defgbkidej3iuvg83e.mp4" are wastes of time. But even if somebody is too lazy to name files or otherwise identify them, one can always take a screenshot of a file directory showing large thumbnails. See the torrent at https://www.gaytorrent.ru/details.php?id=f5e714be77ffffae3f627acd8bc2072fd16a697a1e147c1d for an example. (This looks like a screen grab from a Windows directory; Macs probably have something similar.) Note that each clip also has some kind of description…whether from the original source or renamed by the uploader.
As one of the commenters above said, it's inconceivable that someone would upload a file and not be able to describe its contents. If there isn't a description on the source website, then write one yourself. I realize that this is a very international site, and that not everyone is proficient at writing in English–but even a one-sentence attempt with some grammar or spelling issues would be very much appreciated. For many languages represented here, your attempt at English is likely better than my attempt at your language.
