Some video streaming sites do the whole per-connection limiting thing, which is annoying when you want to download multiple things to watch later (especially really long playlists).

Normally I'd say that accelerators are abusive, but being forced to download hours of video in near-realtime is such a pisstake that I'm willing to make an exception (the alternative is to download multiple videos in parallel, which is even more abusive, yet less frowned upon).
