So is it necessary to notify about cookies, and when?

Question

HTTP Cookies

1) I know that EU residents need to be notified. But what is an EU resident? Registered person? The one who came from the European ip? The same question about the law on personal data in the Russian Federation.

2) Why don't YouTube, VK, toaster and a bunch of other big sites notify?

3) And does this mean that I, as a European, can go to a 2007 site that uses cookies and sue him for not notifying me about it?

Answer 1

3) yes
2) jurisdiction outside the EU
1) only IP is known, so IP
reinsurance - you can do everything, well, or by language))
or all IPs in the EU and those whose country cannot be determined
