Marker.io automatically sign comments your users write when they are logged in with their account information.
When a logged out visitor comments on the public link of a Marker.io issue, we ask their name and email and sign this comment with their info.
Because a malicious visitor might claim to be a user by identifying themselves with a user's email address, we add a warning symbol below some messages to flag that they may not be from the user.
To remove this sign, the visitor must sign in to their marker.io account and comment on issues logged in. To sign in, reporters can go to https://app.marker.io/ or via their widget on their website when reporting.
