The 'IP address'. Someone left a bad review on the Your Child Freedom Formula Facebook page, they wanted their money back and accused Sam of being a scammer. She obviously thought she had been treated terribly and was angry, venting. This person mentioned the IP address as being American and asked if it meant YCFF wasn't a British company.
Usually Sam just deletes negative comments, but you can't delete Facebook reviews, so she removed the entire review section from the YCFF Facebook page instead. Within a couple of days she set up a Trustpilot account and asked those around her to leave glowing reviews.
(In practice a website's IP address being "in the US" is completely standard and doesn't mean a thing, it isn't really something that Sam needed to explain. Her reaction and reply was comically over the top but not at all surprising, since you're really not allowed to question any aspect of her operations whatsoever)
