No, I think Lindsay it was the reference to the instant gold promo HH did with some OS CC's. I can't see the rort though, I suggested to Keith he may be interested and supplied a link to the thread on AFF discussing that offer and he said no, he wasn't eligible. No rort there. The only other thing mentioned was perhaps the HH BRG. I personally don't consider it a rort to make use of a published Hilton benefit.
For the record, I have no issue with my post suggesting the instant gold promo being removed as munitalP does have a very good point about H being a sponsor (I've removed my post). Whether or not rort is the appropriate word, I'm not sure. People have used a published promotion to achieve gold. Perhaps some have provided CC details which don't exist, but surely H could have avoided that by making it "after the first stay, paid for with that card" or something along those lines.........
