Which LinkedIn dataset are you talking about ? - Rapleaf used to sell one but I don't think that's available anymore.
Citation needed. There's no reference anywhere on LinkedIn's site to selling data sets at all. The only thing they sell are subscriptions to their site and there's nothing anywhere that indicates any of those include any kind of this data.

If I read this right, Visistat itself says that they aggregate visit data provided by a list of websites that include LinkedIn:
Looking at their live demo it looks like you just sign-in with the linkedin auth and they use the regular LinkedIn API to enrich people information, so it's not anything the average user can't access via Linkedin anyway.
I do realise that lead information is sold, and I've had enough offers to sell my own users (which I've declined) to realise just how prevalent the practise is.
LinkedIn sell a fairly complete business dataset. My point is that a lot of people might imagine they could do this, but probably don't really believe that they are doing this.
Then when you add in Intro's almost constant tracking (vs occasionally accessing one of the sites that sells your data - or LinkedIn on the web) it is easy to see just how complete one would be making that dataset.
I'd say that most people don't really understand believe that this happens and how good (if that's the word) that dataset already is.
