There is only one solution that I know of so far:

There is a new rule in the latest "WeChat Public Platform Operation Specifications" (ps: 2016/04/09)

4.1.1 Subject infringement

Using other people’s registered business names or trademarks without authorization, infringing other people’s exclusive rights to business names and trademarks.

Use other people's names and avatars without authorization, infringing on other people's reputation rights, portrait rights and other legal rights.

Once such infringement is discovered, the offending public account will be cancelled.

WeChat issued new rules on August 28, "Announcement on Terminating the Registration and Use of Some Accounts on WeChat Public Platform"

The content is as follows

According to the "WeChat Public Platform According to the provisions of Article 5.6 of the Service Agreement, in order to improve user experience and make full use of account resources, the WeChat Public Account Termination is hereby issued to regulate accounts that have not completed registration after applying for part of the WeChat public platform, or accounts that have not been logged in and used for a long time.

Therefore, this is another way to cancel the official account.
