That is funny! I know that BU's Metropolitan College is like an extension division of BU kind of like Harvard extension that offers degrees to working professionals! I have no idea why in the world you are receiving this!
In terms of NOVA, I know that they have similar programs to BU's in the Wayne Huizenga (owner of the Florida Marlins and Miami Dolphins) School of Business. And they have part-time CS and busines degrees which are not good programs! So I do not know why you are getting spammed from both schools. The undergrad at NOVA is very small, by the way.
I have lived both in Boston and South Florida previously so I know what spam you are getting!
