Unfettered was a voluntary group formed in 2004 to run educational and entertainment events in the UK to further the cause of BDSM and fetish. Kinkfest 2004 was the first event. All profits go towards underwriting future events, and beyond that to other organisations for the sole benefit of the BDSM and Fetish communities. It has been established as a Company limited by Guarantee.
It does not seem to have been active since 2008.
