Some searches / categories just become cluttered and completely unusable due to certain users literally spamming useless videos with wrong tags. There need to be a way to filter away those users' videos as the only way to exclude all their videos from your search / category is to exclude the search / category you want to do, which obviously doesn't work, or try to filter by a dozen different useless tags which just becomes a huge hassle and makes me use a different site instead.
