Ask if they belong to that influencer community. If not, they should frankly mind their own business. The influencer’s community should be the one to decide whether they bring value or not.
When I see yet ANOTHER journalist write negatively about an influencer, my first thought is whether the journalist belongs to that influencer’s community.
If not, I think they should frankly mind their own business. If the influencer’s community accepts them the way they are, that should be enough. And if you’re not from that community, I’m not sure you can really understand the relationship.
