A rich communication services (RCS) system may receive a message associated with content. The message may be transmitted by a first user device and destined for a second user device and associated with content. The RCS system may receive subscription data associated with a user of the first user device and including information indicating whether content filtering is enabled for the user. The RCS system may determine whether content filtering is enabled for the user based on the subscription data, and may process the content, when the content filtering is enabled for the user and with a machine learning model, to determine whether to filter the content. The RCS system may perform one or more actions based on whether the content is to be filtered.
