I’m a member of a hate group. Not any longer, but I was for a few hours. Someone added me to one on Facebook. I wasn’t aware that someone else could add you to a group without your consent, but one day I received 14 email updates from this group which alerted me that I had been added by someone. I quit the group right away. A few hours later someone added me to the group again, and I again quit. Not my favorite Facebook feature by a long shot. This was a few months ago, so maybe they’ve fixed that by now. My trust, however, has not been fixed.
My point? It takes time to build trust, but only a moment to lose it. It’s an important point for people, and businesses, to remember.
