I have started reading the Terms of Service of the websites I always use and noticed quite a few of them say you should not use the website if you are under the age of 13 even if you have parental consent. For example, section 12 of YouTube’s Terms of Service says:
You affirm that you are either more than 18 years of age, or an emancipated minor, or possess legal parental or guardian consent, and are fully able and competent to enter into the terms, conditions, obligations, affirmations, representations, and warranties set forth in these Terms of Service, and to abide by and comply with these Terms of Service. In any case, you affirm that you are over the age of 13, as the Service is not intended for children under 13. If you are under 13 years of age, then please do not use the Service. There are lots of other great web sites for you. Talk to your parents about what sites are appropriate for you.
Twitter and Facebook also have similar clauses that discourage people under the age of 13.
I want to know your opinion of these companies having a clause that discourages people under the age of 13 and what you think of having a clause in your own website’s Terms of Service.
Also what about parental permission? (this is separate as I am pretty sure most people would want children to need permission)
