To start with, in xxmai's sheet, NHK WORLD–JAPAN currently has four dramas on it, and as it is for the world outside Japan, everything on it is English-subbed. So I think it should be movedout of the 'Other' and into the 'Regular Sites' tab.
GagaOOLala does not have only BL content, it has only LGBT+-related content – sometimes, rather vaguely and loosely related at that (as in movies that have some homosexual characters among them but they aren't the only central ones).
In the few months since the service was first mentioned here it's taken a very abrupt and unfortunate turn into gay softcore pornography, such that one could be forgiven for thinking on the evidence of the front page that it doesn't cover anything else, and it makes me embarrassed to subscribe to or recommend something I was at first so excited about. But the stuff that's relevant to the other letters of the acronym, and as mild as U-rated, is still there, too.
As well as fiction and documentary series and movies, it has a few variety shows, though as they're original ones which aren't on MDL I don't know if the box should be ticked for that or not.
What would be really helpful (though not essentially easy to implement) to prevent service's YouTube channels and the services themselves being confused would be if the form to submit a link only accepted URLs with 'youtube.com' or 'youtu.be' in it somewhere for YouTube channels, and blocked such URLs being entered in it for anything else.
