I remember when I registered newly here. My email was visible and I was receiving generic messages like;
"Hi, I'm from bitcoin forum, can we get to know ourselves"
"Hello, how long have you been in bitcoin"
I was surprised why I was recieving them in my email instead of in the forum pm. Until an established member advised me to hide my email address.
Most times we overlook the basics and concentrate more on the secondary and lose the primary.
Email is hidden by default now when you register newly and issues like this can now be avoided. Some few newbies still make that mistake of enabling their email to show publicly thou but the risk of getting their account hacked is still very minimal since hackers are not interested in newly created accounts.
Likewise, do not save your passwords in the browser, since all your cookies can be decrypted, and others can get the password for the forum.
Some of the browsers we are use today are very deliberate in stealing people's data by asking them to save the password on every platforms they signed in or registered in. I must also confess that I have fallen for that in the past by saving some passwords on browsers. How do we get rid of these passwords on browsers? Does deleting them means they won't longer have access to it? If not, then it's a trap set against users.
