`you-get` is currently experimenting with an aggressive approach to handling issues. Namely, a bug report must be addressed with some code via a pull request.
https://github.com/soimort/you-get/commit/75b44b83826b3c2d9a...Maybe they got too much spam.
By the way, `tests/test.py` seems to just run the extractors against various websites directly. I can't find where it's mocking out network requests and replies. Maybe this is to simplify the process for people creating pull requests?
