do posting on youtube this way leaves footprint?
When working with a closed API you always leave a footprint.
* Closed as in you need to register an API account / APP.
Whatever its for twitter, facebook, youtube or instagram, you always have to authorize an app to manage your account and give it different permissions of what you'd allow it to control.
Nothing different for this one. In the video you can see:
If youtube see Hydravid as a blackhat tool and keep an extra eye on the application and its users is another story, but the footprint is there.
How do you skip the need for API authorization?
- Use zennoposter and emulate a browser.
- Use fiddler and spoof the traffic, save the csrftoken and use GET/POST requests.
- Same as above but spoof their mobile app instead.
The 3rd option is how you for example register accounts and upload photos through your computer to instagram, I used PHP/CURL.
I wouldn't consider any of the solution to be noob friendly.
