Officially employing a few employees does not increase trust in the seller. One might think this is an attempt to give the appearance of legitimacy to fraudulent activities, but there may be other reasons.
The seller has a single office in the city of Domodedovo. This is not an indicator.
The formula for assessing trust in a seller takes into account more than 40 criteria: from public reputation and reviews to information about the company’s official revenues.
