Dear adamartis,
Greetings from team eBay!
We are sorry to know about your eBay account restriction. However please note that as per the "Service standard policy — bad buyer experience rate" if the BBE rate is much higher than the peer market average, eBay decides to take action. Sellers may be subjected to various actions as specified on the policy page.
We would request you to please contact the eBay customer support and seek their guidance on having your account activated.
Regards,
eBay Team
