Bitcoin and porn are my favorite anonymous things. It want these both anonymously. I have already spent lot of bitcoin for buying subscription of porn content in many sites. Thanks to bitcoin for providing me to buy those without my credit cards.
There is an issue with using Bitcoin, instead of credit card to make payment for porn sites. If you use a credit card, then no additional age verification is required. But if you use Bitcoin, you might need to submit a scanned copy of your driver's license or passport, to prove that you are over 18 years of age. So in the end, Bitcoin is not that anonymous as well.
Do we need to submit identity proof to a porn site? That's ridiculous. If I was ready to my proof to mtgox 3 years back, I would have bought good sum of bitcoin for cheaper price. So, asking identity proof to a porn site, I will google some free sites and free stuff.
