They don't really have much to promote so for the sake of promo variety, I don't mind. Marathons can be important especially for the declining cable TV. Cartoonito isn't the only channel spamming just one show. Half of the channels currently on cable have marathons.For new episodes premieres, yes, it's ok to do that (for show premieres overall they can even do it one whole month in advance, as we saw with the new Gumball and RS sequel series). But NOT when it's for unimportant and passing marathons IMO.
