Just my two, but the web is IN NO WAY anonymous. Anyone who says it is, needs to stick with bitcoin investing and stop talking out their arse. Once you pay someone to host a site, you have left a money trail.
There are dozens, if not hundred web hosting providers that work with anonymous payment processors and/or Bitcoin. Some even advertise that their hosting is completely anonymous.
Which is why there are so many scam sites about.
BTC is too good an opportunity to resist for these people. With the right knowledge you could have a site up and running within hours. If you buy one "off the shelf" it's potentially even quicker than that.
