Scrappy Doo actually help boost the ratings of Scooby-Doo for a while but when they started benching characters like Velma and Daphne for him that's when people started hating him and then James Gunn's movie nuked the character from orbit and he was never able to recover.

Silver is more Cousin Oliver, a new young character created to bring in ratings but everybody hated him and soon the series died after he was introduced and he holds the blame for it.
