Question

网站被Google侦测到是Compromised site, 不能被推广？这种问题怎么解决？或怎么排查？

A compromised site refers to a site whose code has been manipulated to act in ways that benefit a 3rd party, often at a detriment to you and your users. This can include injecting javascript that transmits user data without consent, installing malware on end user devices, launching pop-up ads, redirecting users to websites they did not wish to visit, altering the end user experience, and doing things with user data without the end user’s consent.
