On the topic of link clicks and Muta, I don't think you should really trust those traffic source trackers. I've known people who bought ad clicks through multiple platforms and the number of clicks the platforms reported in comparison to tracker reports varied incredibly. So either every social media site is lying about clicks generated, or every tracker is wrong, probably both have problems and both can be heavily manipulated. It's the same with view counts on videos, shit changes both up and down as there's probably no great way to effectively track every unique click or view, so there will be some extrapolation occurring as well as manipulation.
