I'm not sure why she said that - it's true that I can't take action over on SR myself, but I absolutely do report to DPR and inigo daily there and here. As for figuring this out, unfortunately bitcoin transactions like these do not happen in escrow, and so are not supported by SR. What that means is, if someone IS scammed, there is no hope of getting payment returned (in part because the buyer is not paying in btc when they're buying btc ... and that the only action that can be taken is if Support investigates the vendor after multiple complaints and decides he/she is a scammer. Other than that, SR Support doesn't provide support for these transactions.
