With so many 'news' forces lying or spinning, its great that someone isn't and actually has integrity. Children can see lots of violence in growing up in this ultra violent society. For another to use this as a teaching tool is not wrong.
Don't be fooled: this site is in no way safe. They delete inappropriate content when they get around to it (provided someone flags it), but they just can't keep up.
In terms of vendor reliability, the only thing I can think that youtube sells is video promotion, where you pay for them to promote your video so it can get views. With a site being accessed by so many people and so popular, privacy seems a bit iffy.
Strona zawiera treści nieodpowiednie dla młodych ludzi do lat 16 . Spójrzmy na polskie filmiki takie jak Pani Danuta - Policja Ochrona i Komuna . Video powinno mieć zabezpieczenie +18 ! Jest naprawdę wiele filmów tego typu ! Strona jest raczej przeznaczona dla osób z naprawdę złą kulturą osobistą ... nie polecam jej młodym widzom w wieku 5-12 lat .
