i don't see how this helps...
IMO every user should know (or at least should be able to figure out) what type of content is popular in a given tracker.
furthermore, they should also know how to short out leecher/seeder column (almost all trackers have this feature). It is instant...can short of torrents based on leecher number the very moment...that little click is way faster than coming to FST and checking on this thread.
P.S. majority tracker have guide on ratio for newbies (totally different thing than this but imo it is far better and informative)...there is no need for ratio boosting in several trackers (this thread is pretty much worthless for those trackers)...some have sticky torrent which are pretty popular...some have specific category which are pretty popular, say rosub category in romanian tracker...some have permanent freeleech on certain category (user would locate them way faster in browse page then in this thread).
i can see how this might be useful for big trackers like waff, cd but that's about it.
edit: If a tracker is big then ratio shoudn't be hard to maintain, regardless of your speed (well unless it's like 5 kB/s).
