I just removed the WordPress Shareaholic plugin after I realised it injects unwanted content and external links into my site. See the screenshot below where it adds an unwanted link to KUpdates. In full honesty, would it be a link somehow related to what I write about, but this is about someone expecting twins! Unbelievable.
Anyway, according to some other bloggers out there, the same plugin also injects unwanted tracking code and provides information on your visitors to other sites. I recommend everyone using Shareaholic to remove it immediately
This is the story of an originally nice plugin gone totally bad. Hopefully WordPress.org will also take a stand and remove it from their plugin directory. For sure it is gone forever from my sites.
