My rewiews are not being posted - WHY

Hi there team, I've been an avid user of imdb since - forever, it feels. I use imdb ratings to decide whether I will watch a movie or not. I also post reviews on movies. Granted, as is psychological standard in our society, I post negative reviews significantly more often than likable ones. Well, that's the nature of man. So how come at least two of my reviews (Fall of House of Usher and The rule of Jenny Penn) were not being posted, presumably because they were not favorable? I use no cussing or the kind, I do tend to be somewhat facetious. Not a reason to ignore my contributions, I think. unless you are partisan to anyone in the business. If so, please let me know in your disclaimer so I don't bother anymore. No offense. Anyway, still enjoying your page. Regards. Christian
