There is a lot of interesting information available about influencer profiles:
In the 'Requests' tab, if you click on the influencer's name, her / his profile will appear on a right sidebar.
From here, you can check out about their age, location, Influencer Marketing activity, previous reviews done, the acceptance rate on average, etc...
You can also find general information on their activity on social media if you scroll down in their profile (audience demographics, other networks etc.).
Everything you need to make your choice is here👌
