I have only just seen all this and I am shocked and disgusted. Lowest of the low.
However, for the avoidance of doubt, just because you are in BDSM doesn't mean that you are prone to doing sick shit like this. This guy stands alone in that respect from anyone I know - sub, dom, dominatrix etc.
Whilst I am a dom and am very much into BDSM with a fully adult partner (currently 32 years old) it does not follow that I'd have anything to do with vermin like this other than an exchange of BDSM related opinions on here on a public forum for all to see.
Hopefully most on here will be able to put clear water between harmless consenting pursuits between fully grown adults and this unrelated and sick abuse.
I'm done. Just wanted to make things clear.
