Companies and brands buying followers has really become standard over the past few years.
The real problem IMO are 'influencers' with fake/purchased followers who try to use their supposed clout to hustle free product and money$$$
I handle social media for a consumer products brand and get requests for free stuff or money in return for posts or stories all the time. From influencers with tens of thousands of followers, but then their pics get under 100 likes. IG Audit is a great tool and works really well, especially for a free tool.
Would be interesting to get stats on some skate influencers out there...
