Then the Alerts, by types of notification - are key to where or what is sending your bell all that information.
This may not be from this site - but outside this site pinging the site trying to track you down.
I don't know all your details nor is it necessary - I just don't get those dings, rings, pings and things to bother me - so I'm just as curious to know what is it in your profile making you so attractive to them?
I mean - if you registered at a site to be notified of when someone follows you - this site receives such - using some type of identifier - usually Email address. You registered on-line at a kiosk to win a car - pretty much gives that site the license to track you down and follow your habits because in acceptance - their fine print you gave them your name address and email address as authorized to be used in and during the promotion in the hopes of winning a prize. Doesn't always mean they turn that other site off - once all the prizes have been awarded.
Is your phone tied to any business address like eBay or PayPal - those sites can use this site to ding you - because they have your email and authorization?
So, if you're buying a car, or have an Amazon account or Google "hangouts" is trying to follow you - I can see where these pings turn into "dings".
