I've seen that before too and personally I think at least half of those so called rights are hot air at best and what I usually call "Schwurbel" (meaningless words put one after the other to build a sentence that sounds nice but makes - surprise, surprise! - no sense).

Some of it might be interesting and helpful for someone very, very, very new to BDSM and/or someone with a very low self esteem.

That being said I think it's quite sad somebody once thought it necessary to write such a bill of rights.
