It will work for as long as your IP is valid.  They can also ban the
entire IP block (aka, your ISP)

Your browser will not (or should not, anyway) reveal your "computer

User-agents and referers.  Some browsers can send quite a bit of

It could also be a content filter between you and the web site in

pornography.
