Oneboxing YouTube videos triggers constant requests to YouTube’s servers. Confirmed repro conditions where I can confirm my own browser sending requests are:
- Sharing a video that’s a part of a playlist along with the playlist. Sharing the video alone without any references to the playlist seems to be fine, at least on the clientside.
- Sharing a video with URL of the form
Looks like a problem with additional parameters.
The main concern is that this might trigger a violation of YouTube ToS, specifically:
you agree not to use or launch any automated system (including, without limitation, any robot, spider or offline reader) that accesses the Service in a manner that sends more request messages to the YouTube servers in a given period of time than a human can reasonably produce in the same period by using a publicly available, standard (i.e. not modified) web browser;
If I oneboxed that video instead of blockquoting the link, I would generate a total of 668 requests by now, one for each character I typed. And that is not counting me fixing typos. Which I did have to do multiple times.
I consider this a bug personally, but I’m posting in meta since the feature does work as intended. If the intention is to spam YouTube’s servers that is.
