You didn’t specify why you chose this name. I removed it in case it was the name of an AF member, just to be safe.
Is it really critical to your point that we know exactly who this person’s name is?? Is that what you’re arguing? Because it still makes sense even with initials.
If you specify where you got the name from before you post it, or perhaps include the link to the public page, and it doesn’t appear that you are outing an AF member, then it’s more acceptable:
“Hey look at GMO’s managment: It has Jeremy Grantham…”
