Long back Orindum posted a trick on Taj hotel. Book a hotel and then cancel it later. But the cc gives you rewards and the money is refunded too. It worked for few and later for a guy, they didn't refund the money stating some TnC. So this guy lost ~30K for mere 1 or 5% rewards.
Cases like these are what I call OBGM - Orindam Bhaja Govindam Moments.
Incident 2
There was one more case where one buys from a website and cancels, request refund to the bank account. This way they earn cashback on cards without spending. The merchant later changed TnC and says he will cut 10% in the refund amount.
Incident 3
As said above pay to self account as rent by cc to earn cashback. Now his money is stuck .
All these cases where 'shikaari khud shikaar ban jaata hai' following Orindum are what I call OBGM
Incident 4

I pulled a drishyam for you in 3 independent enqueries for the dreaded z mod word.
On the first instance, I convinced the mods that you meant kuchbhi gen Z mod.
on the second instance, I convinced them you meant samsung z fold model
on the third instance, I convinced them you meant zzz mode in phone.
Perhaps you are the only one who didn't get ban for using the z word so many times , because of me protecting you.
