At this time there are performance and cacheability impacts of blocking members everywhere that preclude us from doing this. In the future we would like to address this better.Jack Verhaeg commented
When you block somebody on letterboxd, you should not be able to see them on the website at all, especially on the film's landing pages under 'popular reviews.'

Love the list feature, but i would also love to see the option for more versatility with them - for instance, it would be great to create a list of 'Best Actress Nominees,' or Actors that have starred in a film by a particular director - even a list of directors with similar styles, or a letterboxd user's favourite director!
