Wady czatów - sprawdzenie

Proszę o sprawdzenie i poprawę błędów.
I agree with the statement that chat sites are bad for young people. They are very dangerous for teenagers. We don't know who is on the other side of the monitor. This person may be a pedophile. Young people also spend a lot of time chatting. They west their time they could devote to his hobbies. Sometimes they become addicted to chat sites and difficult them to find friends in real life. I think that "real" friends are better, because they always help us.

We don't know who is on the other side of the 'monitor' (wiem co masz na mysli, ale moze jakies inne slowo - end of the line?) .
Young people 'also' (nie wiem czy 'also' jest tutaj potrzebne) spend a lot of time chatting. They 'west' (nie, tu masz zle slowo) their time (tu brakuje slowa np WHICH) they could devote to 'his' (zle slowo, jak mowisz o 'they' l. mn - to tutaj tez musi byc l. mn) hobbies. Sometimes they become addicted to chat sites and (tu brqkuje 2 slowa) difficult (tu brakuje slowa) them to find friends in real life.
