How to use 'Disable ads' with 'supporter' plugin?

Hi,
I have problem with the ' Disable ads' .
After I install the 'supporter' plugins, i do a trail test. I found out in one of my supporter blogs,
1) there is a 'disable ads' button in the 'support' admin
2) I pressed the 'disable ads' and pressed the 'search'
3) a long list of blogs ( that I have created via my mean blog) shown and is allowed to 'disable'

What that mean,
'Search blogs, Find blogs to disable ads on them'?

How does this work?
In what purpose do my supporter need to do with this list? if they have rights to disable other blogs?

Thanks,

Lillian
