For the last few days, VideoUpload keeps stopping my downloads, accessed via KissAsian and other sites. I prefer to use the sound option where you identify a few words. However, the sound option now believes that I may be automated. They put up a refusal saying to try later (one hour isn't long enough), 

When I go for the visual tests where you click on the motorcycles or hydrants or crosswalks, it presents multiple screens. Last time there were at least ten with four being duplicated. That's 50+ clicks for a single episode.

Why does a downloading site make it so difficult to download?
