I ask because I'm not surprised at all that there's slavery among BDSM aficionados, but it is supposed to be consensual, and Larry himself asserts that every slave relationship is consensual in the communities he belonged to, as of 2017: https://www.garfieldtech.com/blog/tmi-outing
So forgive me if I've misread your implication that any of this was non-consensual or forced. You didn't say so, but you seem to be implying that.
