店铺因为侵权被封。但邮件里没说清楚，我不知道是哪个listing违规了？

这是我在Performance Notifications收到的邮件，除了这个，没别的了：
"We recently contacted you about your listings that may infringe the intellectual property rights of others. The listings we removed can be seen on the Performance Notifications page in Seller Central. Because you continue to infringe the intellectual property rights of others, you currently may not sell on Amazon.com."
亚马逊没说是哪个listing侵权，所以我不知道该怎么办
