突然のebayからメッセージにより制限がかかりました。
私はこれからどんな行動を起こせばこの制限から解除されるのか、ご教授いただけないでしょうか？
よろしくお願いします。
Restore your selling privileges: Action required

We restricted your account because we noticed activity that we believe is a risk to our community.

This restriction means the following: 
- Your selling privileges are temporarily restricted. You won’t be able to create new listings or revise any listings that are live on our site. You also can’t register a new account at this time. 
- If you're a seller participating in managed payments, we are withholding your future payouts. You’ll start getting paid again after you resolve your restriction and your account is reinstated.
- Some of your listings may have been removed. You’ll find details of any listings we removed below. 
- We have credited any associated fees except for any final value fee for your listing(s).

To help us remove the restriction on your account, you’ll need to:
- Provide proof of delivery for all of the items you sold on eBay by uploading tracking. Track items you've sold. 
- Resolve any outstanding issues with buyers through the eBay Resolution Center.
 More specific details are provided below.

Once you complete these requirements, reply to this email, and we’ll review your account. We may ask you to provide additional information during our review.
