Why might probationers and parolees want to limit their social media activity? give an example of a circumstance in which a facebook posting could cause probation or parole to be revoked?

A probationer may have agreements or conditions during a probation. Monitoring is given to this person and also it becomes the basis for good behavior. If so ever in this agreement, social media activity was prohibited, it becomes a call to revoke a probation and to send the person to jail. There are already some cases where this had happened, it only proves that agreements during probation and parole are taken seriously.
