I think it's much less work on SpecialInterestTube. On YouTube there's a huge amount of decisions and ideas the moderator has to take into account. The other one can filter a large amount of spam with "the first 5 seconds make it clear it's not SpecialInterest".
For example comparing to HN, I can go on "New" and see "Places to Spray a Fragrance on for a Long Lasting Effect-Ajulu's Thoughts" - I know it's immediately flaggable, even if it could be a valid post on another website. (and require a full review there to check it doesn't break some specific rules)
