Technically anyone can host their own webserver from their house. (Turn an old box into an FTP, forward the DNS/IP to a domain, etc). But that would mean if the site went down we'd only have one guy working on it (whoever owns the house the box is in, lol) rather than an entire team of network experts (commercial hosting companies).
Let's just face it, CG is for CG stuff. If you want to go watch porn (if you're of age of course, Cadaver
), go to a porn site. If you want to partake in other illegal activities online, do your own thing. But keep CG out of it so that people like Cadaver can keep the site appropriate and friendly for everyone.
