I agree with what zipplet said. Its disheartning to look at whos connected to a torrent and see how many have downloaded lets say, for example, 500mb and only uploaded 50mb. I hear there are even clients now, that can make your upload nothing, and allow you to just leech uncontrolably.

Well i guess some leechers can't be helped. Myself , i hold myself to a sort of torrent ettiquite. If the torrent dosen't have more then 10 seeds, ill stick around for about thirty minutes or so.

Also, something thats happened to me, dunno about others is that after about five to ten minutes after connecting to the torrent, your speed will gradually increase.
