The thing that annoys me most is people listing their run-from-home business on the map. This is explicitly against Google's TOS but they don't stop people putting them on. You can flag them, and Google do remove them. Scan your neighborhood, click any business which is clearly actually a house, click Suggest an Edit > Close or Remove > Not open to the public. I've had a lot of success removing a whole ton of spammy junk from the map this way.
