Should there be an agerestriction  on social media

The Internet is really usefull, but it has some really bad sides like cybermobbing, aggresive Videos and pornography. Children watching some of these things dont understand the consequences it can bring. Older People are more mature and know the consequences. But still I dont like the idea of having an age restriction of 18 years on the Internet. It can help to contact people, it can help for learning in school and a lot of other things. I think there should not be an age restriction on the Internet, but there are programs that can avoid children to go to specific pages. Those programs should be used more. 

BETWEEN LIFE AND DEATH

Amanda Todds terrible experience with cybermobbing:

Amanda Todd was a normal girl who destroyed her life with just one little mistake. I think its terrible how affective the Internet is now a days. With just one photo everybody started hating Amanda. She moved Schools and Citys several times but nothing changed for better, instead it got even worse. She couldnt trust anybody and if she did, it would end up terrible. I cant understand how People can hate someone so much that they just want her to die. Not even one Person tried to help her and she must have felt so alone that i understand her reactions. I think if only one Person would have felt sorry for her and would have helped her it would have ended up different.
