As a KOL agency, what I really want to say is:

Actually, KOLs are all amateur operations
Many people take on ads just to take on ads
When projects are handed to them, they don't do proper due diligence at all
Many just casually put out copy without effort (even top-tier KOLs do this)
Many even act like they're above it all
Like they think project teams should be begging them to do promotions
They've all been spoiled!
Acting like big shots, but actually don't even understand the projects themselves
Many project teams have said that a lot of KOLs (including top streamers) don't seriously do their research. Ask them to post a promotion, throw a few thousand dollars at them, and they just phone it in
Not professional at all, no work ethic either, acting like the project teams owe them something
Talk with real ability to deliver—honestly, there are very few who can actually drive volume
