People have been putting those little files in for years, the only thing that's changed is that now the destination sites are bittorrent trackers with adverts and the txt files are poorly spelled and ugly, whereas back in the day they'd have awesome ASCII art advertising the various scene dumpsites the release had been FXP'd through.
They still have those ASCII art and scene dumpsites. Problem is that someone with access to scene material takes that, and then retags it with their shitty website and uploads it to bittorrent.
What a shame that their beautiful art which they invested time and energy into is being misappropriated by someone else so that they cannot profit from their creative endeavours.
