I've also been asked by other users for this request in - https://play.google.com/store/apps/details?id=com.vanniktech.rssreader&hl=en&gl=US - and so far I haven't found a good solution. Some people want to have an allow filter, some want to have a deny filter. Some want the filter to be global, some want to have them only for certain feeds. Some want different keywords for different feeds. It's all messy and non-straight forward.
