For the most part, you are right.
I’d make an exception for writers who work for a blog/magazine/paper that requires excerpts of everyone.
Just a personal opinion, but I’d probably make an exception for some charitable organizations— wounded veterans, childhood cancer, etc.
I find the ones to excerpt right where Jim Robinson and the Admin Moderators list them.
