The blacklist of general libraries will be automatically eliminated after one week, so you don't have to move out, just wait for one week.

Add blacklist: If you don't want someone to appear in your contact list, click "Manage Contacts" in the lower right corner to enter the management interface; Click the corresponding contact, and then click Edit Contact-Add Blacklist on the right to add it to the blacklist. The blacklist of email chat is different from the blacklist of address book. People on the email chat contact blacklist can still send you emails.
