Lol. I've seen this before in Facebook and they're making it a meme. Personally, I don't get why would someone even buy that thing!? I'm still in my right mind and I would never think of buying such thing. I won't waste my bitcoin on a stupid thing. I didn't worked hard to earn bitcoin just to buy bath water...
I have no intention of offending someone who buy this kind of thing but I just really have no idea what's the point of buying it?
Where there is demand...
Funny thing is that all of this can be faked, just fill some tap water maybe add some "fragrance" and boom! instant "gamer bath girl water".
This of course is unrelated to Bitcoin, she could have set up a paypal account or such.
Do you remember that bot set up by some German? that would blindly buy random things from Silk Road and they would place the items in a kind of museum? That thing bought all sorts of weird things, such as fake passports, drugs and so on.
At least selling her own bodily fluids shouldn't theoretically be illegal... Well i can imagine some entrepreneur hiring some hot model for publicity, and start selling all sort of things that actually don't come from her but nobody can audit.
So besides being a seriously ridiculous idea, chances are very high you are getting scammed and getting some ugly woman fluids or worse... (not like you can ever tell the difference, anyway... pee is pee).
The used underwear thing i have heard before, in Japan some places buy and sell...
