I've ended up going with the API for saving comments seeing that there isn't much time left. Difference is that it won't get whether comments are hearted but will get exact creation and edited timestamps. Older videos are unlikely to have hearts anyway, especially if they're abandoned as unlisted videos.

It uses a lot of API calls, but it seems that the universal API key being used isn't having any problems for now. In any case, I've given the script to someone with a lot of proxies to cycle through, so probably not going to face any problems at all.

If you've got a list of videos you'd like comments saved, I can pass that along and get them back when this whole thing is done.
