Amex Nectar Card question re transfers to online gaming website

dharm999

I'm looking to get an Amex Nectar card, and trying to boost my Nectar points balance as quickly as possible. I read somewhere that if you have a credit card that gives you Nectar points, then you can boost your Nectar points balance by transferring between the card and an online gaming site your credit limit, then a few days later transferring the amount back to the card. This can be done as many times as you can practically do in a month. You have to do a small amount of gambling on the online site, but insignifcant compared to the Nectar points you would earn. The cc company sees the transfers to the online gaming site as spend on the card and you get the appropriate amount of points for this spend. The transfers back to the cc are seen as paying off the debt on the card. Would the cc company see the transfers to the online gaming site as cash, and therefore charge for it as a cash advance on the card? Is this really possible without incurring lots of bt fees? It seems extremely unlikely that this is possible.

Thanks for your help.
