There are always a few bad apples out there that cause problems for the rest of us. This is actually something Mavrck is building safeguards against. Essentially when an account authorizes in the Mavrck platform, we get access to all of their data, including: every single post on Instagram, 90 days worth of posts on Facebook, and lifetime post data on Twitter and Pinterest.
Mavrck is currently building the capabilities to crawl all of these posts and look for the same comments on multiple posts which can then be tied back to those "fake" accounts. We will then flag them as questionable and have a human take a closer look.
One of the reasons we have focused on Micro-Influencers is that there is far less fraud among the everyday consumer vs. those folks who are trying to make a living by accepting cash payments for posts. Additionally, it is still not effective to buy fake followers and comments at the micro-level. We are currently looking at 3rd party integrations that will add a second layer of data on the audience of our influencers.
As with any evolving space, there will be folks that take advantage of the rising tides, something we are keeping a close eye on.
