I think, the problem here stems from making vomit draft a social technique instead of keeping it at a personal level. It is potentially harmful if other people can read it. OP describes it as a personal method and it may work by breaking some psychological issues, like a fear of under-perform or something like. But to do this one need to overcome all fears, to get rid of anxiety, and it needs a safe environment where you can write anything. Literally anything, to try it and to show to your mind that it is harmless thing, nothing bad happens, it is ok to write not good enough, because you can dump it later.
