This is a very good postand it does make sense, but here is where I see a glitch....I am assuming this comes from "Old Guard" philosophy, before Internet, in reference to r/l community where everyone has been through proper initiation and or training and has consented to that and subscribes to that philosophy...so essentially by implication all participants have some kind of "relationship" in regards to each other (even if they had never met before).
BDSM "community" today isn't where it was 5-10 years ago and compared to where it was 30-40 years ago, I believe, is unrecognizable. The Internet changed things, our society in general has become more lax about what it finds appropriate, BDSM has become (if not mainstream) more visible to general public and acceptable to those more open minded....and in response to social changes BDSMers have become less "conservative", more inclusive, open to everyone who wants to experiment, there is no prescribed training or protocols that apply to everyone,....with so many variables to have a set in stone detailed list of protocols is virtually impossible. Sure it has its drawbacks (one of it being it attracts a lot of fakes, trolls...basically a lot of characters who don't understand this, whose intention is to abuse and exploit those who extend them welcome and trust, from get go), but to paraphrase Churchill, it is the worst form of "government" except all the others that have been tried.
