After a round of inspection work, this site has banned dozens of accounts registered with temporary email addresses, and at the same time corrected a number of incorrect email addresses during registration (for example, fill in gmail.com with gamil.com, and fill in qq.com with qq.con , qq.om, qq.ocm, sina.com is filled with sian.com, etc.), resulting in an invalid email account.
The whitelist mailbox mode is currently enabled on this site, and only mailboxes in the whitelist can register new accounts.
Users who have registered with personal domain name mailboxes and business mailboxes will not be affected.

This site has the final interpretation right of this notice.
