General users do not know how to do all that. There are many other ways to access sites too. Anonymous proxies (not necessarily running on port 80), SOCKS and all which is too tough to block. But most of people do not know all that. And if one is expert to do that, which means that person is doing something which is banned by Government and hence illegal so can get himself arrested.
