I've seen a lot of developers post almost nothing in terms of quality content yet somehow have thousands of followers.
Meanwhile I try to post quality content and only have 600 followers. I have considered buying at some point but decided that I'd rather have fewer real followers than thousands of fake ones. And I've written books and spoken at dozens of conferences...
I can definitely see the argument that if I bought followers and a conference organizer or publisher used that as a metric by which to consider booking me it could be considered fraud.
Here's the basic black's law dictionary definition:
An intentional misrepresentation of material existing fact made by one person to another with knowledge of its falsity and for the purpose of inducing the other person to act, and upon which the other person relies with resulting injury or damage.
I mean, it might make me decide to listen to them a time or two. It won't for long, though - they need to say something worth hearing for that.
(Disclaimer: The previous paragraph is hypothetical. I don't do social media at all, so I don't follow anyone...)
From MW:
* intentional perversion of truth in order to induce another to part with something of value or to surrender a legal right
* an act of deceiving or misrepresenting
In other words, yes, fraud, your ticket to the 8th Circle of hell.
Companies need to do their research and ask the right questions before they part with their money...
