The recruiter’s action in checking the online presence of a candidate is legal, because there is no law which prohibit this kind of action. And it is also ethical, since it is a common way to do online background check of a candidate during the recruitment process. Lesson learned about posting private information online is to share as little information as possible and never share information unless you know why it's needed.
An online background check is a report that is either carried out by a search of Web site databases, or perhaps obtained online through a company specifically set up to produce such reports. The background check may include such things as criminal record and residency history.
A background check is a process a person or company uses to verify that an individual is who they claim to be, and this provides an opportunity to check and confirm the validity of someone's criminal record, education, employment history, and other activities from their past.
