Apologies to Thunderbirds fans but isn't it a bit unrealistic to expect that whoever does the checking is going to be familiar with every anime, movie, TV series cartoon and JapaniPuppetMation that's ever been produced? Unless the item is tagged "Inspired by the Hit Series," or something similar, the only way to catch some things is going to be for people to point them out. No need to necessarily assume sinister backroom deals or favoritism, tempting though it may be.
