It seems to be more of a 'craftsy' sort of thing here in the US. I first saw it on a PBS craft-type show, years ago. It is also on youtube. (rust printing on both paper and fabric).
I don't think that these are necessarily "cheap imitations of rust prints" as the original story states. Just a newer form of an old technique. I have many hand cut wooden stamps and tjaps-both copper and wood, that I use for this type of printing. I also use them for wax and glue resist prints when I'm playing with dyes.
