Sorry for my bad english…
I got an email about my violation of rule 2.8.
I think this is wrong.
I did not cache any mp4 videos.
Why might I have experienced this problem?
I have bot to play videos.
I host the videos on my own server.
Rule 2.8 violated domain is only the domain of the bot where my player is installed.
In short, I have no chance to cache video.
