Question

if we want an email id of a person, how can we get through online? which website?

Answer 1

You can't get the personal data of others like that, unless you know by that person.

There are no such loop holes actually exists.

Any websites can take our personal data(like while registering on sth) but it(the website) has no rights to share with others

Unless the saved data in the PC or Mobile is hacked/lost it is not possible...

Keep rid of any fake websites that say it's possible ..

;)
