What about content?

Internet content is totally uncensored. Because of this, children surfing the Web can be exposed to sexual, malicious, racist and violent content in e-mail messages, chats and forums.
You may find political content that's incorrect (e.g. published by totalitary states) - but even the Senat of the United States does it - they publish "sugarcoated" content.
And what about Wikipedia? Are you shure that every information found there is correct?
Don't believe what you read. Preserve a critical sense for information - or do you believe everything you read in daily newspaper?

Here you have an interesting example: faked diaries of an artist.

Faked identity

Oh that’s really bad – I’m lacking for a new girl friend!
OK, no problem. There is this much frequented chat room – no problem, there is an interesting girl: Fitting age, similar interests – seems to be a fortune. She gives me a description: 16 years old, blond, student of a high school.
We chatted for some weeks. Unbelievable! She likes the same music, she prefers the same films in cinema – I think I have to meet her.
4 weeks later we have our first date. I almost did not recognize her – only the newspaper she had in her hand showed me who she was: About 25 years old, anything else than blond, without work and interested in some guy to pay for her. I had to run away, to flee immediately.

OK, last time for an internet relationship, I will try it the conventional way – Saturday evening I will go out – to town to have some fun with real people.
