I’ve just noticed the one 4 all link in the bio of her Insta has “utm_source” at the end of it.
Which means it is probably being tracked for either affiliate or sponsorship purposes.

Thing is, you need a lot more info at the end of a utm source code for someone to be able to track it and then most people put it into a URL shortner to make it look nicer and fit into social media limits.
Hubspot give a good example of how it should look:
http://blog.hubspot.com/9-reasons-you-cant-resist-list?utm_campaign=blog_post &utm_medium=social&utm_source=facebook
So it tells the people analysing it (usually the company or marketing agency she would be working with) what the campaign is called, the channel they came from and the specific source they arrived via.

For the utm code on her sponsored or affiliate link to be wrong is so unprofessional and is making the lives of the people she is working with really difficult as they will need to report on her ROI for this campaign.
