Everyday,a lot of people use Internet for different purposes.Sometimes,it is used for fun.People can surf on the net,chat with their friends and play games.Sometimes,it is used for academical purposes so we can vary these examples.However as it happens in everything,there is certain restriction about its uses.Some sites are forbidden and closed for different reasons.Some reasons may be acceptable,on the other hand the others may be absurd.For example,parents ban some sites which include immoral or harmful things.To a certain extent,they are right.But is that enough?Can restriction keep children from using these sites?Certainly no! Because children can reach these sites in Internet cafes.That's why parents must inform their children about harmful sites.In addition this,some sites are closed for politicial reasons.It is absolutely ridiculous inasmuch as people can recognize transverse ideas.There is no need for restriction.
