This user sold me 5 WHMCS licenses in return for 0.02BTC (It's not a lot but hear me out).
Upon buying these licenses, he managed to get me 5 licenses reasonably quick. Just to be safe, I contact WHMCS to check out the licenses. Upon validation from WHMCS they seemed to be valid. But, WHMCS then asked me if I'd had bought these. I replied saying Yes I have. WHMCS then replied with this:
No, these are not one time licenses. These are webhost licenses and they cannot be resold. Thank you for bringing this to our attention.
My keys have now been Suspended and I have wasted my money. These ARE NOT ALLOWED TO BE SOLD! DO NOT BUY THEM!
