I would for anything truly extreme (like some horrible shock footage in the middle of a supposedly innocent video). But I don't know if all of these videos actually violate any rules; often they are of the kind <title: THING YOU'RE LOOKING FOR>, where the content is actually someone talking about the thing I'm looking for.

edit: Or another relatively common type, not necessarily fake or even strictly misleading, just cynically low-quality: a video made by pulling some text content from the web, feeding it through a speech synthesiser, and playing that over over the top of some 'relevant' images.

When you are reporting a video there is "Spam or misleading" option but then again you are left with YouTube algorithm deciding whether video is really "spam or misleading" or it is malicious report.

For the past couple of months I was regularly reporting group of spammers spamming links in comment sections but to this day I still see them running amok.

Given its Google, I assume those get forwarded to /dev/null
