thats a lot of rhetoric, dancing and mostly irrelevant personal history and experience to counter one thing you said initially:
"GC is like cash advance"

Its not. Its product that Chase sells. While I can come up with several ideas why someone might need a bunch of GC, business Inks are not the only cards eligible for this offer. There are CSP, UA, etc.
Everyone here has his/her own tolerance for risk - nobody has to prove what is valid business or personal use, nor does chase usually asks about it before shutdown.
Some people get gray hair waiting for $500 to come via USPS, others are activated 40+ cards.

What exactly is "fair" on a forum called "Manufactured spend"?
