What is adding #.Wbb--------- to all product links?

[alwayspaws]

I put dashes in place of some of the characters in case it's specific to my site. What is making #.Wbb--------- get added to all the product links, please?

Thank you. Mystery solved.

@mdekker Is it necessary or can I remove addthis since I have social icons built into my template already?

[alwayspaws]

Is the "get social" section of icons the "addthis" icons?

On my product pages right under the product I have the following buttons that have their name and icon: Tweet, Share (FB), Google+ and Pinterest.

I have the "get social" icons in the footer for the whole site.

It's confusing!
