It started couple of months ago that youtube started displaying user gmail email address in the comments. I mean if you are viewing a video and decide to comment on that video then when you comment you will see your gmail email address being displayed as username that who posted comment. Well this is very risky you should know that malicious bots can crawl comments and get your gmail address from it. So Question is how we change it so that whenever we comment then our actual gmail address is not displayed there in comment section. Well its pretty however not many people are aware of it. Visit : https://www.youtube.com/handle and click change handle button and then enter username other than your actual email address. after that happy and safe commenting.
