I got Spam from a site I visited. How does a web site get my e-mail address?

Maybe from your web browser.  (I’ve condensed the answers after scouring the web; includes excerpt from article by Uri Raz.)Some sites use methods to extract a surfer’s email address from their browser, sometimes without the surfer noticing it. Using the HTTP_FROM header that browsers send to the server, some browsers pass a header with your email address to every web server you visit. To check if your browser simply gives your email address to everybody this way, visit http://privacy.net/analyze/.They can use JavaScript to prompt the browser to send an email to a chosen address with the email address configured into the browser.  Some browsers would allow email to be sent when the mouse passes over some part of a page. Unless the browser is properly configured, no warning is issued.Also, if one reads email through a browser, they may be subject to active content (Active X, applets, Javascript, etc.) or web bugs.Besides the browser, another way is using finger daemons.  Some are set to be very friendly.  A finger query asking for john@host may produce list info including the login names for all people named John on that host.  A query for @host can produce a list of all currently logged-on users.

  1. Hi! I know this is kinda off topic but I was wondering which blog platform are you using for this website?

    I’m getting fed up of WordPress because I’ve had problems with
    hackers and I’m looking at options for another platform.

    I would be awesome if you could point me in the direction of a good platform.
