  Impersonators on Online Social Networks such as Instagram are playing an
important role in the propagation of the content. These entities are the type
of nefarious fake accounts that intend to disguise a legitimate account by
making similar profiles. In addition to having impersonated profiles, we
observed a considerable engagement from these entities to the published posts
of verified accounts. Toward that end, we concentrate on the engagement of
impersonators in terms of active and passive engagements which is studied in
three major communities including ``Politician'', ``News agency'', and ``Sports
star'' on Instagram. Inside each community, four verified accounts have been
selected. Based on the implemented approach in our previous studies, we have
collected 4.8K comments, and 2.6K likes across 566 posts created from 3.8K
impersonators during 7 months. Our study shed light into this interesting
phenomena and provides a surprising observation that can help us to understand
better how impersonators engaging themselves inside Instagram in terms of
writing Comments and leaving Likes.
