Hi, I know there is already a guy posted a same questions but i found it that there is response from anybody.
So I was thinking to show an example of this error, the example is from the addthis.com example in this website.
Please visit this : http://www.addthis.com/labs/floating-horizontal-bar
* first you logout with your twitter account (web).
* click http://www.addthis.com/labs/floating-horizontal-bar
* click the DEMO tab
* scroll to show the sharing buttons
* then click the twitter button (http://www.addthis.com/labs/floating-horizontal-bar)
* observe + counter, it will increment even if you are logout from your twitter or even if you cancelled the sharing in twitter popup
Currently our software will count shares that are cancelled or if the user isn't logged in. We're working on checking to make sure the share went through.
