Introduction   I will again start with a disclaimer that these are the rules for and do not apply to any other site. The cutoff in item values for which we expect traders to complete a background check is 15 keys value on either side of the trade (so, for example, if you buy a 30 key hat for 14 keys you still need to do a background check). For trades under 15 keys in value, we do not require that you complete a background check. Feel free to post any questions or concerns
