Two problems - this disavow tool is not prominent in webmaster tools, second - have no clue how long it takes. Recently I found TONS of obviously spam links pointing to my site and tried to use this tool. After two weeks - no noticeable results. I.e. no feedback.
Overall - whole no-feedback nature of your SE is what bothers me the most. Just put rules upfront, give some feedback to webmasters and ignore seo gamers.
