Will it be harassed to activate Zhihu's phone number?

It's hard to say, it's best to install Tencent mobile phone housekeeper to intercept. On the security protection page of Tencent Mobile Manager, select the harassment interception in the upper right corner and select Add to Blacklist.

You can either choose interception mode or intelligent mode in the settings, or only accept the white list, and you can customize the settings; If there are harassing calls in the middle of the night, you can turn on the housekeeper's night anti-harassment mode.
