I’d start by saving the inappropriate message and reporting the account before blocking it. Then review Instagram’s privacy settings with your son: make the account private, remove unknown followers, restrict DMs from people he doesn’t know, disable location sharing, and turn on two-factor authentication. We also agreed he could show me anything uncomfortable without automatically losing his phone, which made him more willing to speak up. A reputable family-safety app may help with screen-time limits and alerts, but hidden chat monitoring isn’t foolproof. If you mention uMobix instagram tracker , disclose the connection and check its privacy and legal terms.
