Mike,
??? I don't understand "reports a message"
Members can "report" group content which they feel violates the
group's rules, or the Groups.io TOS. The Report function is in the
More menu, in the bar below each message:

This brings up a form where the member can enter their complaint
and choose whether to send the report to the Group owners/mods, or
to Groups.io support.
