I think some people are getting wiser to fake followers; one client asked me recently about types of followers, whether I was followed by any journalists or influential people in my area of work, rather than just amounts, which was interesting. That's the first time - for me, anyway - that there's been any depth to a question about social media.
It's amazing that more people haven't focused on fake followers since it's so easy to find out this and so many people do it. I guess it's laziness, but hopefully as people adjust to the changing influence and get wise to the tricks people pull, there will be more consideration given to how someone promotes their brand as opposed to just how many people are aware of their brand.
