Is Engagement Monster safe?

Clean risk

Engagement Monster opens hidden Facebook tabs to react to posts and submit configured comments.

Engagement Monster stores user-provided comment templates and timing settings, then opens inactive Facebook tabs to run the automation. On Facebook pages, it waits for the configured interval, follows post or reaction URLs, clicks reaction controls, fills comment textareas, and submits the forms.
