I don't think, category ... has huge evaluation queue.
Basically, you're speculation about something that (1) you have no way of knowing and (2) is irrelevant.
Reality is, entertainment categories get LOTS of made-for-ad-banner spam sites: the entertainment field is basically made for/by advertising. So your basic assumption is quite possibly wrong.
But what does it matter how many suggestions a category gets, anyway? There are billions of sites on the internet, and EITHER (1) all of them are on your topic, in which case your first assumption is definitely wrong, or (2) some of them are on OTHER topics, and you're expected to permit the volunteers for reviewing them anyway.
In either case, your uninformed speculation is no excuse for violating the submittal policies.
