If the smart matches are there to help, and not advertising for My Heritage, as a source citation, then I think they should be hidden in a tab.
If people want more information, they will click that tab.
The iFrame is slow to load, buggy, and ugly.
It would only take one copy and paste of the code to move it to a less intrusive location.
People are serious about their profiles and management, and this is an insult to their work and pride.

PS. Many are complaining, many will not match, and some will not merge to a page filled with these ugly images.
