Question

I use this command for downloading videos from Pluralsight:

youtube-dl --cookies cookies.txt -o "C:/MyVideos/%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s" URL --write-sub --sub-lang en,es

But after a few times my account is blocked. Do I do something wrong ? Or how can I avoid blocking as much as possible ?
