Hi, I have the email address of one person! I also know the password, but I can't get in there, because Google does not know my laptop / mobile phone, and I would like to send confirmation code if I'm really that person.
Can I prevent this?
No idea but no, because you have lost nothing in the e-mail account of a stranger without a good reason!
It has a very important reason it is about fraud!
I think it's good that you can't do that (hopefully!).
Can you prevent your project?
This is not a page for "Please COMMENT NOW IMPOSSIBLE" I do not need ethical opinions but help! You do not know what it's all about
Knowing what it is about would make it easier for us to weigh the meaningfulness of our comments.
Oh, cheating on whose side? The owner, whose data you want to come from, or you who wants to get involved without permission?
What do you call yourself in your action, if not on ethical / moral grounds, when you speak of 'fraud'?
