Not Sure What This Means On My Posts

Not sure where to post this but notice that in the right hand side of my posts\new threads\replies there is a small purple\blue square with the message- "Grant Mack has disabled reputation" (& other peoples posts on the same thread have similar symbol).
Can anyone explain what this means?
Regards
Grant Mack

You will find that in the menu bar at the top..

Thanks for the response.
At least I now Know that I wasn't being blocked for be a Nerd!
I am a complete novice\virgin when it comes to these things- absolutely no idea of "Face Book" or "Twitter" but discovered Woodwork Forums a couple or more years ago and only got the courage to become a member back in January.
I do find it a very good and comprehensive site for exchange of questions and information and enjoy the banter and lack of disparaging comments about other contributors I have seen on other sites I used to visit on other hobbies.
Again thanks
Grant MacKinnon

Thanks for asking the question, now I know the answer, as well.
