Embed HTML on User Profile Page

I'd like to create an HTML block on each of my users profiles that only the admin can edit. (I need to update with a HTML) embedded badge each time they update a blog site.) Is this possible?

No. Not really. I think you are assuming all members have their own separate profile page.

All profile pages are generated on the fly by script pulling information for the specific member from the database to populate the profile page content. There are no seperate pages to work with.

You will need to do the same thing for your block. Information for each member will have to be stored in the database.

As such an html block cannot be used. A PHP block would be the only way to accomplish this and would require PHP programming skills to pull it off.

You will most likely need to hire someone to do a custom module for you.
