This is an interesting examination of how Russia is using social media as a PR tool:
In the case of @IamTyraJackson, the IRA’s goal was two-fold: Grow an audience in part through heartwarming, inspiring messages, and use that following to spread messages promoting division, distrust, and doubt.
I don’t know how you really battle that, other than to be aware that anyone you don’t know on social media, may not be what they seem, and to be wary of assuming someone who is tweeting uplifting messages is always looking to be uplifting, they may be just trying to sweet-talk their way into your feed so they can then seed it with messages meant to get you to distrust, or “otherize” people who don’t agree with you.
Of course, we could also argue that this article was written to make us distrust Twitter users, right? 😉
Go read the whole thing and see how they are working on us.
