The only way to communicate with an admin is to send a detailed message to BG support. If you have an problem with a particular record or image, you must give them the complete URL for that site. If you want them to remove information, you have to give them specific reasons and how you are related.
This Community is for the users to help each other with various questions, but no one here has the ability to remove records once they have been entered and transcribed. Only BG staff can do that.
Hope this helps,
